Help with wobble at 55mph!

Im in desperate measures with my jeep no one seems to be able to figure out why i have a wobble in my front end at 55mph...i have replaced damn near whole front end..tire rods.u joints, track bar, shocks,steering stabalizer,front control arms upper and lower, i have a 4 inch lift on my jeep..put a go pro underneath and mechanic says its in my left tire. The damn jeep got so bad i had to pull over and couldnt go over 40mph...the mechanic i brought it to got the fixed that dw..but at 55 it still wobbles then it pulls out of wobble after you pass 55..please help i cant get this shake out of my vechicle...even at the jeep dealership they cant figure it out..so it sits its im not driving it

 

Thank you! I would hope the mechanics would check that. .tried it with other tires and still shook though

 

Also have tires with spacers..do u use lock tight on spacers? My spacer came loose on the left tire which is where all the vibration starts..

 

You could try removing the spacers and taking it for a drive, if it fixes it great if not, on to the next thing

 

So....the current issue: Does it pull the steering wheel back and forth like DW does or is it more a vibration?
Can you post the video you took?

Taking a stab with the info I have now:
As a general statement, what you describe (if a vibration) pretty much has to be centrifugal in nature. In other words...tires/wheels/hub/axle...etc., something that turns when the vehicle rolls. The most common would be tire balance and alignment.

I know you said you changed tires but did you change wheels? Did you have them balanced. Did you rotate the wheels to different locations? Have you had it aligned? As well, carefully inspect the wheel spacers. If one is worn (around the studs) from running loose it could be out of center.

Just some wild, but experienced, guesses.

Good luck!!

 

Thank you for your help yes i have had my tires rotated balanced and aligned... The mechanic tried a different set of tires he had laying around..amd still wobbled..yes its more like a tire shimming now but thats what started in the first place then led to the full on wobble im trying find the underlying problem..before the DW comes back..the mechanic tried to tell me that jeeps just shake like that..BS..could rotors be an issue?

 

My rims wont fit without spacers

 

I would suspect that anything spinning could be the issue. But...unless somehow the rotor got out of balance I can not see it. (I would think that would be something easily visible.) Unless the rotor is somehow out of center, that is. That would require the holes be worn to the point it could be tightened off-center (also should have been easy to see.) Something bent could do this. Like an axle tube. A bad hub could do strange things but I have to assume it would have been detected by now with all you have already done. I did not notice BALL-JOINTS on your list...worth checking if not already done. Just for kicks...have you checked your shocks? I have seen bad ones do interesting things.

Ok...I am going to go back to a DW issue real quick "just in case". Have you loosened and then retorqued the bolt on the axle side of the track-bar? It needs to be torqued to 125 ft-lbs. This little bolt causes all sorts of crap for people with JKs. It must be done on the ground but a BUNCH of mechanics torque it down while the rig is still on a lift so it is really common on modified rigs. This generally causes the vehicle to pull to one side more often than not too.

Also...time for a new mechanic IMHO.

 

Ball jionts and shocks got replaced..i think your right this mechanic is not working

 

If he says all jeeps have this issue then it is unlikely he will be aggressively working to fix it for you.
I wold like to see the go-pro video you took. I know you have already seen and analyzed it but I am curious.

'Cause here is the deal...if you have checked everything that could possibly cause this...then you missed something along the way.

Did all this just suddenly happen or was this in close proximity to adding the lift?

No helping apparently but, I am trying. lol

 

I have to get video from the mechanic. It was his go pro..it always had a little vibration but now its just horrible..i will post it when i get it. I appreciate all the imput..the lift was on the jeep when i got it.....i think im gonna get wheels that fit this jeep remove the spacers and change rotors out..they are pretty rough looking..im hoping prayingthis will cut the vibration. I believe he tried different wheels before he changed my whole front end..so all those parts are new so i guees try to eliminate the rotors and the wheels after that ugh any suggestions given im willing to try...agian appreciate the imput..

 

It is ok if you can't get the vid...I was just curious. Sorry to not have been much help. There is likely something so obvious it is getting looked past. Photos of your rig would be useful (I hope).

It sounds silly but are your axles centered side to side and equal on both sides for front to back? We have already had one jeeper on here whose rear axle was off center.
Inspect your spring packs carefully for cracks and your hangers for anything odd.

Also...just as a project...has anyone removed the front drive shaft and driven it like that as a test?

If we are grasping for straws...might as well go all out.

 

i had the DW after putting the 4" procomp on. changed out to a currie HD TR and alignment. went away. what about your wheel bearing? or KNuckle joints?

 

I like Paul's idea of getting rid of the spacers. If it were me, I'd borrow a friends wheels/tires that you know are good, remove the spacers, to see if that fixes the problem. If it doesn't then you have made another check mark on your list and you're not out any money. It seems like your mechanic might not be completely truthful. He may not have actually tried another set of tires. I have had bad tires that could not be balanced because of defects in the construction of the tire. They would balance and after one drive they would be out of balance again.
