Front end pop

[DaveS98]

My ruff-stuff heims are only like 3 months old..surely they arent worn.
I tightened the shit out of all my links last night, tightened the tb a bit more than it already was, ensured all the TRE's were tight, took some rope and tied it under the loose shock bushing so its not floating around.. Seemed a bit better this morning. Ill take it out on lunch and see if its still popping.

I bought rough stuff heims and they didn't last me a month before they came loose, they are not even close in quality to FK rod ends. They are cheap, thats because they are poor quality. I am now running evolution joints on my uppers and they last a long time before they need tightening.

When my upper control arm heims would wear out I would get a quiet pop I could feel in my feet under excelleration from a stop.

You probably won't have wear problems with your suspension joints like I did since your running a 3 link "less bind", but I found those heims to be poor quality for me. FK rod ends lasted much longer on my 4 link and the adjustable evolution joints put the FK rod ends to shame!

Check your leaf spring bushings. My original Rubicon Express leaf bushings were completely disintegrated in less than 2 years. Inner sleeves were completely free from what little rubber remained (outer sleeves were snug in the leaf eyes). Popped while turning and whenever the rear axle loaded/unloaded.

Plus it never hurts to remove and re-torque those leaf bolts every couple of years. I'd be upset if one completely seized up.

Axle u joint is still making me think...
Unless my steering box brace is ****ed.

The lift is literally 3 months old, everything was brand new when I installed it.
I held the brake down while giving it gas to see if the motor mounts would pop under the torque..nothing.

 

[MrShaft696]

just out of curiosity do you feel it in the steering wheel?

 

[DaveS98]

Dont feel it in the steering wheel.

It may very well be the LCA heim on the x member side. I grabbed the arm and was able to shake it one good time and replicated a similar POP. Once i did it the one time it wouldnt ever do it again though.

Wheeled today and now I have a couple more pops going on. Gonna be picking up an entirely new D30 this week so Im gonna swap some parts around and see if I can pinpoint it.

I'd say try replacing the trans mount. Mine is probably doing the same thing, now that I think about it. It's the original piece and probably half fallen apart by now.

What about control arm brackets? Maybe they are moving, not the arms in the brackets.

 

[DaveS98]

The brackets are welded to hell. They arent moving.

Seriously, check your leaf spring bushings. I had a nearly identical clunk. Energy traveling through the front of the leaf spring sounds eerily like the front of the vehicle.

As a test, go to a parking lot and accelerate to around 15 MPH. Brake heavily and keep the pedal mashed even after coming to a stop. Release the pedal quickly and see if it pops as the axles unload. Check in reverse too.

 

[DaveS98]

I will do that.
Gonna be pissed if the bushings are shot so quick, 3 months and maybe 1500 miles.

I drive 3 miles a day..thats it. Other than when I drive to the trail.

RE leafs...
