WJ - Front axle loose, clunky Pls read - detailed - Search Completed :-)

I searched!

Let me start by saying thank you for reading.

WJ Details:

Tires- 31.5
Lift-KOR BB with Up Country DT8000 Shocks (hub center to fender 21" = 3" lift)
Track Bar- Stock with no axle side hole issues
Transfer case - Select trac


Issue/s:

While is 2 wheel drive the "front end" seems loose (not death wobble, but bump steer) if I put it in 4x4 fulltime everything seems to tighten up... BUT issue 2 is still there.

Issue 2

really issue 1 - Front right, passenger side suspension travel is very clunky. I really do not want to start replacing things and spend money without fixing the issue. Let me explain... Oh all TREs replaced

at times if i travel slowly, rolling over speed bumps I will here a clunk on the down travel... This sound also is prevelate while driving down my friends driveway on his farm... dirt, gravel washboardy

And on the beach

just clunkiness on the downtravel


Thoughts

Everything is tight or appears tight

No tire movement 12 and 6 or 9 and 3

LCAs?
UCAs?

I am looking for the experts to help out. I can take some flaming to make it a good tread

Thanks

What happens in Part time 4x4? Are you sure this really fixes the issue??

Get under there and see if anything is tight. Grab the control arms and wiggle them. See if you can move your tie rod and drag link more than usual. Is your trac bar tight with good bushings?

I do this weekly.. just something to deal with on a lifted jeep.

I would consider an adjustable tracbar.. My axle was not centered with the UC + BB combination.

Agreed it was more a bump than anger

To answer the other questions

I cannot move anything I will throw out my back before anything moves.

Now the track bar is interesting. it is stock and my axle is not centered.

4x4 doesnt 'fix it' it does feel a bit tighter up there. bump steer goes away

What about your sway bar bushings? Those make a nice mysterious bump/clunk when they are worn. At first glance they may look aok, but you have to inspect them carefully.

Interesting about 4x4 though... not sure what to think about that

couple of things:

1st get a HD sterring stabilizer to handle the bigger tires, that was the cause of my bump steer.

2nd at 3'' you need the following: adjustable track bar, extended links ,and shocks for a 3'' lift. if you bought shocks for a 2'' lift they might be to short, most of the time shocks that say 0-2'' lift are about the same lengh as stock.

Bump steer can also come with a loose steering box. Adjusting it made a world of difference for me-

*edit- I replaced all front control arm bushings, front bar links, tre's, have good shocks. Still had bump steer till I tightened the steering box.

OME HD Stablizer installed - Still have bump steer

Shocks are: 8000 Pre-Runner

Extended links for the front - Is that really needed? Track Bar is on order

Could the clunking be a broken coil spring? I would check the spring, most commonly they will break at the top or bottom rather than in the middle anywhere.

2 cents spent.

Check upper and lower control arm bushings (or have somone check for you)
Check all ball joints
Maybe check shock? (I got a bad one from Rubicon Express it happens)
Are you sure all TRE’s are torque to spec? maybe one came loose?
Check caliper bolts.

That’s all I can think of at the moment.

Ball Joints would be my guess...I would start checking them. Jack up wheel and put a pry bar (a 2x4, etc...) under the wheel to try and pry it up. Watch the ball joints for movement. IMHO 1/16" is too much movement. Anything more and you're way too much.

That would make sense since it happens on the down travel... so probably the upper Ball Joint.

Would a bad ball joint make noise while back then hitting the brake ***clunk***?

Again thanks forum

If you get clunking while braking either check the brake caliper bracket bolts or the Control Arm bolts and bushings (bushings need to have the CA's removed to properly inspect them).

Thats good info...

I do not get the clunk going forward only backing... or rolling backwards and tap brake quickly and firm...i.e back out driveway clunk


or back out of the drive and rolling off the 'ramp curb' (driveway to street transition)

I am thinking it is one of these

CA or Ball Joint

I took off the caliper and reinstalled same noise

UHG - I want to run this into a brick wall - But I love it..its still a baby 113K on the clock
