Bent axle??

Hey guys
I had 33s on my tj until today.. I finally got 35s. I've always noticed on my rear driver tire that it wobbled side to side a lot. I never worried about it mostly bc I figured it was just the all terrains and because hey its a jeep. When I got the 35s today I noticed that the driver rear tire wobbles just the same. Is it a bent rim, Bent axle, or is it the fact I have a 6 inch lift with no adjustable track bar and my axle is pulled all the way to the passenger side??? I had my gears redone and and rebuilt front and rear and it was wobbling befoe and after. They took my axles out im sure they would've noticed if one was bent. Whats the deal???

Likely bent the flange in rear axle shaft. I wouldn’t expect the gear installer to notice a bent flange. I just replaced both of the chromoly shafts in my rig because the flanges were bent. Only takes about an hour to replace both shafts.

Try swapping on a different wheel to verify that a bent wheel isn’t the culprit. Not sure what rear axle is in your rig but I wouldn’t dump a bunch of mo dy into a D35.

If it was a bent wheel and you have had the wobble for a good while, it would have changed positions when you rotated the tires. If you have rotated the tires even once since you noticed the wobble, it's not the wheel.

In a similar vein, I had a slow leak in he RF tire of my Ram 2500 years ago. I had not bothered to fix it, just air it back up every 3-4 days. After I had my tires "rotated" at the dealership during an oil change, the slow leak was still the RF tire. The dealer has not been allowed to rotate my tires since.

You can drive on it. It will pretty much ruin that new tire after awhile. There is of course the outside possibility if it is the axle that it could fail at some point (meaning your tire and rim come off).

Switch the tire on that location and see if the wobble moves with the tire or stays there. That will determine if it is the wheel or the axle. If it is the axle, you could probably find a used one for whatever rear you have if you don't want to purchase an aftermarket set.

If it's wobbling, I am surprised you can't feel it.

are y'all sure it could be because its lifted so high without an adjustable trackball . it makes the left rear tire almost turn to the inside somewhat. I really feel like that might do it . ill send a pic of what im talking about. look at the driver rear tire

Regardless of the track bars holding position, the track bar should be holding the axle still in that position. If it is broken, worn, or damaged, that is a different story.

You are saying you see a "wobble" and not just a tire sitting crooked as it is rotaing right? If crooked while rotating, it may mean that your axle HOUSING is bent or something is up with the position of the axle. A wobble usually means a tire or axle shaft is bent (or loose lugs), a cocked wheel means it's the housing most of the time.

With your Jeep lifted without relocating the track bar it would throw the axle off center but should not cause a wobble. The control arms will only move the axle forward if to short. I would jack the Jeep up and set on stands and spin the wheels to check it all out, you should be able to hold a square on the floor next the the tire while rotating it. This should show if there is a wobble. If there is try rotating your front wheel to that position and see if you still have it, if not it is your wheel if it is still there it most likely is your axle flange. If your wheel is bent and has a visible wobble you should be able to feel it as well. You did not mention feeling the wobble? You can also do as others have mentioned and rotate the wheels to see if it is bent. My thought is that it is unlikely that when you purchased new tires the tire store would have mounted your tires on your wheels and installed your wheels in the same position as they were with the old tires. Also they should have found the bent wheel when they balanced them. You may also want to have them recheck, a good tire balancer will show the bent rim if the operator is paying attention.

If the shafts are indeed bent then now is a good time to upgrade the D35 to a super 35 kit. That axle isn’t going to survive long with 35” tires if you beat on the rig off-road.

Jeeps don't wobble just 'cause they're Jeeps. Something ain't right. Find it. Fix it now while it's still small. It will only get worse. I think I'd also be looking for another mechanic. No tellin' what else he's willing to shrug off

X2. Saying "its a jeep" is a horrible statement that to many people use as an excuse to be lazy.

If it's bouncing a lot and that's what you're seeing instead of a true "wobble", it could just be worn out shocks... quick and easy replacement.

"Its a jeep" wtf! Never had a jeep that rode like shit, if your jeep is f-ed up figure it out and fix it! Jeeps don't ride like shit, shitty owners make jeeps ride like shit. I have had more 4x4s and jeeps than most, and can tell ya, most people who talk like that probably just trashing a good vehicle due to ignorance.

no offense man but... if I still had a stock or maybe two inch lift and small all terrains like you I wouldnt have this problem and would except a better ride . in fact its always been like this since I bought it but with the huge tires its just more noticeable. wait until you lift it 7" .... then u have to accept a 21 year old vehicle with huge modifications isn't going to be a perfect riding Cadillac .


lifts and big tires do crazy things to a vehicle. I know what the problem is . bent axle . but im just gonna drive it until it breaks then drop a 8.8 in it or beef up Both of the axles

I've ridden in a jeep based buggy on rockwells and 50" tires that rode and handled great....

There is absolutely no reason yours can't be perfect....
35" tires, 7" lift" 21 years old.... meh.... tain't nuttin but a thang.....

If it's done right it'll work right....

Doesn't make sense to me to damage new tires before fixing... also keep in mind that although hopefully unlikely, a bent axle IS a compromised axle and a failure at the wrong time COULD cost someone their life....

You can get complete D35's for $150. Get one from a stock rig that's not wore out and swap the axles over to yours. Problem solved and you are not gonna ruin your new tires. Or spend alittle more and get a set of chromoly shafts for the D35 and be in alittle better shape. Also....for a small amount of money get an adjustable track bar and center that rear end. For less than $400 you can fix both issues.

yea they rear end being centered to me isn't a big issue. I can order that axle for $130 from rough country. its so slight tho y'all it wobbles just a little more than the rest of the tires. I really don't wanna spend the money. All my friends and even my brother just drove it and said if It was his jeep he wouldnt worry about it lol

Its your Jeep...do what you want with it. A bent axle will cause other issues....brake wear...tire wear...compromised axle integrity. Why ask for opinions if your are going to do nothing about it. I have to imagine that the trackbar is causing excess stress on the already thin factory brackets and joints because it is fighting the axle location all the time. It may last awhile....it may not.
