Front end vibration... still. :(
 

Summary: 2002 TJ Sahara, front end vibration coming from the front
passenger side between 60 and 70mph. Smooth ride below and above that
range.

I've replaced: track bar, passenger-side axle u-joint, passenger-side
wheel bearings, passenger-side ball joints (holy crap -- THAT was an
ordeal), sway bar, sway bar links. New springs, new shocks. The tie
rod is solid and not loose. I've had the tires balanced. I've even put
other wheels on there to make sure that wasn't the problem.

And the vibration, while a lot less than before, is still there.

I'm out of moving parts, and almost out of money. Any other
suggestions other than "drive it off a cliff"? :)

Re: Front end vibration... still. :(
 

How do you know it is coming from the front passenger side? That is
about impossible to test for when driving.

Due to the solid front axle, the vibration could be coming from either
side or even the driveshaft u-joints.

I had one harmonic front end vibration that I swore was coming from the
passenger side and I went after parts like you did 'except' I tested the
parts before changing most and only changed parts with obvious play. My
Jeep had 295K on it at that time.

Well even after some new parts like the track bar, it got worse to the
point I thought my tire was going to fall off or it almost felt like the
'death wobble' so I stopped and checked my wheels.

When it got this bad, the failed part finally showed up by taking a
piece out of my fan shroud. It was the damn clutch on the radiator fan!

The amount of vibration that came from this failed clutch was amazing!

Re: Front end vibration... still. :(
 

Just because the tires static balance doesn't mean they're not to blame.

Swap the rears to the front and see if the problem goes away before you
take out a 2nd mortage to pay for other unneeded parts.

I'm almost positive it's coming from the front passenger side because
that's the side that things keep breaking on. I had the passenger side
sway-bar link self-destruct, and the passenger side shock (Rancho)
literally fall apart. The track bar mounts on the passenger side were
also mangled and had to be replaced. The lower ball-joint on the
passenger side was jammed crooked into the yoke so badly that I had to
drill it out to remove it (drivers side looked nothing like it).

I'm not 100% sure, of course. :) The vibration is almost definitely
coming from the front, as it does seem to hit the steering (it almost
feels like I'm about to lose control -- and it vibrates up into the
steering wheel)... but in such a short wheel base, it could be coming
from the back .. I guess this is wishful thinking, since (to me), the
front axle is a hell of a lot simpler than the Dana 44 rear.

I've also put the manual transmission in neutral and coasted down a
hill at 65 mph, and the vibration remains, so I'm sure it's not a motor
mount or something related to that. I also have coasted down a hill
with the transfer case in neutral, and once I reached 62-63, it started
a rythmic bouncing until I hit 72-73 and then it smoothes out. If I
drop to around 65, it stops. If I get below 60, then back up to 62-63,
it starts again. (yeah; super unsafe, but I was getting super
frustrated).

Of course, I don't know if putting the transfer case in neutral
actually isolates anything important or not. I suppose I could
completely disconnect the front diff from the transfer case to test the
drive shaft u-joint..

Tonight I'm going to do a tire rotate and move the front to the back,
back to the front, and also swap the brake rotors on the front to see
if it changes the vibration...

After this, I guess I'll be swapping parts on the driver's side
(u-joint, bearings, ball-joints)... if that doesn't work... the inner
axles are just about the only thing left.

If anything, these parts are all nearing the 100k mark, so it's not
hurting anything to replace them, anyway.. :)

Go have them spin-balanced.
most tire shops static balance them. You know the little air bubble in
the center hub of the tire mounting machine.
If you loose a wheel weight it can cause a shimmy. maybe not noticeable
at all speeds either. Could be only in the 45 to 60 mph range.

Hmmmmmmm I haven't had a tire static balanced in probably 20+ years.

I KNOW that you had them balanced, but did you ROTATE them tires too?

oh yeah. I've even borrowed the wheels off of a friend's
(non-vibrating) TJ and put them on mine.

I replaced the brake rotors today, as one of them was too warped to be
fixed. No difference.

I'm going to try disconnecting the front drive shaft and see if that
makes a difference.

nope. no difference on the front drive shaft.

rear drive shaft is next. sheesh.

Not the rear driveshaft, either.

Wow. Uh...

So...

- Had three different places rebalance the wheels/tires
- Replaced passenger side wheel bearings
- Replaced passenger side u-joint
- Replaced passenger side ball-joints
- Replaced both front brake rotors
- Replaced trackbar
- Checked and double checked all bolts on the front end and rear
- Checked and double checked tie-rod
- Pulled and checked steering stabilizer, it's still solid
- Disconnected front driveshaft
- Disconnected rear driveshaft -- so it's not a driveshaft or u-joint

I'm completely out of ideas now... :)

Have you checked the motor and transmission mounts?

What about the harmonic balancer (lowest pully on engine)
make sure it's not walking off. Those can make vibrations
if they start to separate and rotate around the rubber isolator.

Did you check the fan on the radiator for clutch play? It will wiggle
if bad.

It is amazing the vibration that can come out off that little sucker
like I mentioned. It got bad enough I thought my passenger front wheel
was going to fall off and I had to pull off the highway to check it.
