Re: 4" lift 33" Tires
 

Hey Patty, (or anyone else) If I get both front and rear axle, would it be easier to swap the axles then change the diff's?

Thanks

Re: 4" lift 33" Tires
 

what are the numbers

Re: 4" lift 33" Tires
 

I would just swap axles thats what I did that way you don't need to set gears up. unless ball joints are shot.I think it was quicker to just swap axles. What motor is in your jeep now ?

Re: 4" lift 33" Tires
 

First the numbers on the rear diff are as best as I can read. As soon as I can confirm they are the 4:11's I will pick them up at the wreckers.



53008521
11605423-1 (tag has been cut off at the -1 and needs to be -11 for the 4:11 gears according to the Dana web site)
-1 is a 3.07 gear. Is that possible in a 90 YJ 4cyl?.....Help

The motor is the 4.2l 6cyl. I just tossed the Carter for the Motorcraft and now I need to do a nutter bypass and timing. Its a bit sluggish so i'm hopping that works.

Who comes up with "Nutter"

Re: 4" lift 33" Tires
 

next thing to do is to take cover off and find the numbers stamped on the crown gear. or count teeth and do the math

Re: 4" lift 33" Tires
 

crown gear should have 37 teeth and pinion 9 =4:11

Re: 4" lift 33" Tires
 

So I changed the carb and did a nutter bypass and still no power. Is it all in the gears???. I'll change them but I had my hopes up that the carb and the nutter would give me enough power to enjoy the redults of my labor. Thanks for doing the math for me :)

I meant to say in my last post, the motor seems to run fine, good power until I engage the transmission.

Re: 4" lift 33" Tires
 

Before I change everything in my Jeep I could hardly use 5th gear. I have 4in lift and 33's as well.

I recently installed the juice box Team Rush upgrade and its running a lot better. The front and rear axles are indeed 4:10 gears so the wreckers are pulling them out today. Install hopefully in the next couple of weeks. Wreckers also has a transfer case and transmission that I thought I would pick up if its the same or better.

I would have to find some numbers on those and look them up before I buy.

Oil leak under the fuel pump ???? i AM READING THAT IT has happened to some jeepers. Picked up the mech pump and will install on the weekend.

This fixing up a jeep is more fun than I had originally thought. Thanks for your help.

CAnt wait to install the gears
