Quadra drive won't work!
 

Hello I'm new to the site. And I have a huge problem
I bought my 01 jeep gc limited about 2 months ago
And the Quadra drive was working perfect then I took
It to canadian tire for inspection and they said I needed
A cv boot so they changed out the whole axle the front
Passenger side. And ever since then the Quadra drive
Won't work I get stuck everywhere and they won't fix
The problem they keep saying it's fine but clearly only
Rear wheels spin. Is there any idea what it can be or
How to fix it?

Re: Quadra drive won't work!
 

Might be the sensor on the passenger side shaft. Is the abs light on?

Re: Quadra drive won't work!
 

No the abs light is off. And when I put it in 4 lo the back
Wheels just spin more

Re: Quadra drive won't work!
 

From what I can gather on the information I have available (which is not much) When the system is in low range the transfer case is supposed to lock the front and rear output together. To confirm whether the t/case is actually locking or not you would have to jack up both ends of the vehicle, make sure it's securely supported and then put it in low range and see if both front and rear driveshafts spin when you have it in drive. If not it would point to an issue with the t/case which could be a broken wire, fuse or something more serious. If both driveshafts turn but only the wheels at one end it would point to either a differential or axelshaft issue.

Re: Quadra drive won't work!
 

When I jacked it up only the rear wheels spun and
The front passenger but it was really slow compared
To the rear. I stopped the front with my hand so
It wasn't spinning strong at all. This all happened after
They replaces the passenger front cv axle

Thank you for your replies

Re: Quadra drive won't work!
 

Hi Kal07, I'm assuming you have the 247 T/C?
When the wheels are all off the ground in 4hi the back wheels should spin and if you stop one of them one of the front wheels will start to spin.
When in 4lo all 4 wheels should be spinning.
Sometimes (not always) this can be cured by doing a fluid change on the T/C. I know it souds strange but it does sometimes work.
If you do have the 247 make sure you use the correct fluid and nothing else, what may have happened is the previous owner may have topped it up with ATF and the clutch pack inside is sticking/ sliding.
Good Luck

Re: Quadra drive won't work!
 

But were both driveshafts (front and rear) spinning when it was in low range?. I'm trying to establish if the problem is in the t/case or the front diff.

Re: Quadra drive won't work!
 

Just the rear was spinning with the front passenger
But I stopped the front with my hand and it stopped after I let go
It was working perfect until the changed the cv axle right after they
Did that it stopped working

Re: Quadra drive won't work!
 

The last owner was my uncle and he never changed it
And if he did the dealer does all the work
Like I was saying it worked 100% for me
I drove it from bc to Alberta 8 hours in the snow
And it was beautiful. When I went to do a put of province
Inspection they said the cv boot was ripped so they changed
The whole axle and right when I was driving it home
It was fishtailing every where then I figured the all wheel drive isn't working
So I took it back and they lifted it up put it in drive and
Only the rear and front passener tires spun but I stopped the front with my hand
It was spinning so slow. And then they gave me this bs about how
There's no way all 4 will spin at one time an if it did it would
Be hard to turn. I'm like ok but how does it work in a awd then? And
They said oh well jeep is different, so I just left and now I'm stuck


Thanks for the reply

Re: Quadra drive won't work!
 

OK, lets try something else. Jack up the front end. rotate the right side tyre and either the other side wheel or the driveshaft should turn, what happens? Then rotate the left side tyre and either the driveshaft or the other side tyre should turn, what happens? Follow these directions exactly and post what happens, should only take five minutes or less to perform this simple test.

Re: Quadra drive won't work!
 

In park reverse neutral or drive?

Re: Quadra drive won't work!
 

You really need two people to test varilock axles, basically you have to build up the pressures in both the tranfercase as well as in each axle. first test the axle, then test the transfercase.

first thing get it all warmed up, take some tight turns for about 2 minutes
jack up the axle, spin the tires in opposite directions, it should build up pressure and you shouldn't be able to freely spin the other tire backwards, both wheels should spin in the same direction at the same rate... as soon as you stop spinning, the pressure should drop and the tire should spin in the opposite direction again freely...

then test the other axle

one thing to remember about the Quadra Drive is 100% of the power can be sent to any 1 wheel! it can also be at any rate aswell...

and the front driveshaft is what actually primes up the transfercase in the 247, the rear driveshaft is whats connected to the case for sending the output to either axle...

tricky system it is, when its operating flawlessly you dont notice it... testing it is a nightmare...

Re: Quadra drive won't work!
 

Nothing at all happens. Do u think the installed
The wrong axel? The thing that's driving me nuts is
It worked before I took it to ct and then stopped
The second I picked it up

Re: Quadra drive won't work!
 

That's what it sounds like to me.

Re: Quadra drive won't work!
 

So would the select trac axle fit in the Quadra drive? And
Cause it to stop working?

Re: Quadra drive won't work!
 

the axle/ CV is pretty much the same for the axles, the difference is all in the differential.

If they drained the fluid and didn't add a limited slip additive to the oil they could have burnt up the coupling in the axle... adding the additive may bring it to life, but most times it ended up cooked and that would send the whole system haywire...

Re: Quadra drive won't work!
 

Ok so today in Calgary AB it was -28 deg C. With windchill so anyways
I went out and it worked perfect. But after about 30 min of it being warmed up
it seemed like it Was slipping. Really weird. But ya anyone know
If it could just be the oil? And if so how do I change it? And how much
Does the oil cost

Re: Quadra drive won't work!
 

Ok...sounds like it couple be a number of things.

First off, Quadradrive works by sending all the power to the rear wheels until there is a difference between the rate at which the front and rear wheels are spinning. Then it progressively sends more torque to the front via the progressive coupler, until both axles return to the same rate. When the progressive coupler fails in a 247 transfer case, it defaults to rear wheel drive only unless you shift into 4Lo. If the fluid in the case is low / old / or the wrong stuff, it can cause the case to act up or fail...so you could try getting some Mopar 247 transfer case lube (dealership only) and that may fix the problem. There are two holes in the back of the tc which take an allen head. Top one is for filling, bottom for draining. Remove the top one first to ensure you can fill the case back up once drained. When filled, the fluid should be level with the filling hole when parked on level ground.

However, you said only one of the front wheels would turn during testing. Quadradrive and Quadratrac models have different length axle shafts because of the varilock differentials in QD models. Also as stated above, Varilock diffs need a friction modifier added when changing the gear lube. The gear lube is cheap, but the friction modifier suggested is a dealer only product. (some folks have good luck with products like royal purple that have the fm already mixed...) I use standard 75W-140 weight gear oil front and back, with 2.5 oz of Mopar Friction Modifier in the front and 4 oz in the back ...IIRC. Its easy enough to change yourself, just a slightly messy job.

Re: Quadra drive won't work!
 

Ok so I guess it's not working at all. Today what I
Did was a tire rotation maybe that wpuld help it didn't. I couldn't
Just lift up the front end I will tpday but when u lifted on side
The right and it was in park I could freely spin the tire
It felt like a little pull kind of thing but still very easy to spin the tire
I'll change the transfer case oil today or tomorrow how much does it cost?
For just the oil, hpw can I test the system. What I do is in the back alley
It's icy I just get my dad to stand out of the car I put it in 4lo and pin it all that happens
Is the rear spins fast and the front doesn't at all. It just sucks cuz after
Crappy tire touched it the system stopped working and they won't
Touch it anymore or help me put after I spend 500$ there anaywyad all the replys
Are helping so thank u very much meand alot cuz my baby boy rides with me and the wife

Re: Quadra drive won't work!
 

First off, I've never had anything but negative experience with the service departments at Canadian Tire. Not saying they are all bad, but I think you'll be much better off with a different automotive service shop.

You said you were in 4Lo and the front wheels would not turn? That makes me think either its not in 4Lo, or something is seriouly broken (front axle shaft, front drive shaft, or the tc) To shift into 4Lo, let the jeep roll at <5 kph, shift the tranny into N, shift the tc from 4alltime right to 4Lo, then shift the tranny back into D.

Do you hear strange noises when testing? grinding? Does it make a clunk when shifting into 4Lo? Do you notice an increased draw on the engine and higher rpm's in 4Lo?

Re: Quadra drive won't work!
 

I'll try that out today. The way I would put it in 4lo is if I was parked
I would put the car in N then move it from 4all in to N then down to 4lo and
Then put it in D and test it I didn't shift as I was driving.
Thanks againfor the reply

Re: Quadra drive won't work!
 

Lots of grinding as I shift into 4lo and I feel alot
Of force like extra power but still only rear wheel

Re: Quadra drive won't work!
 

... then I think your transfer case may be broken. It may just need an overhall/adjustment...but that might cost as much or more than a new/used transfer case. If I were you, I'd have it looked at by a small mechanic shop nearby, and explain that you think the transfer case is broken. Shouldn't take too long for them to figure out, and if they can confirm that fact, then you can look at getting another t-case from either from a junkyard, or a remanufacturered one.

good luck.
:)

Re: Quadra drive won't work!
 

Damn that's so werid before I took it in to ct it
Was 100% and after all this happened. How much
Does it cost for a tc?

Re: Quadra drive won't work!
 

Can it be the tc chain?

Re: Quadra drive won't work!
 

Yes, it could be. Or the shifting linkage...but I think the cost of getting it removed, taken apart, and fixed will be very close to the cost of getting another one installed.

Re: Quadra drive won't work!
 

I believe my jeep was last serviced at Canadian Tire (previous owner), and i had gear oil in my transfercase, and it takes ATF... and just picked up a VW Beetle that had a "blown motor" or a bent valve... compression test good motor, OHHH it had a broken Catalytic converter and was blocking the exhaust...

the worst part is they never bothered to pull the check engine code, "O2 sensor lack of efficiency" seriously... if that doesn't say check the cat i dont know what does...

i wouldn't get serviced at a Canadian Tire.

Find a small shop in town, find someone that drives a 4wd vehicle and ask them to check it out for you. (like our garage, both myself and the owner are 4wd maniacs)

Re: Quadra drive won't work!
 

Call National 4WD in Calgary, they should be able to reccomend a local shop for you if they don't have a service bay themselves. Wish I was home instead of in McMurray I'd come over and help you troubleshoot it.
