Car Forum / Jeep / July 2007Popping noise when turning
Hello everyone: I replaced my right front hub assembly yesterday, and everything was ok right after, but now I am noticing a popping noise (multiple times, like pop pop pop pop) when turning or swerving at low speeds. Could this be a bad U-Joint? I also have another problem where the steering wheel doesn't go back to center after turning. A mechanic suggested I check the U-Joints. The one on the right is fine, but idk about the one on the left. Any suggestions? Mike > Hello everyone: > [quoted text clipped - 7 lines] > > Mike The mechanic was right.... You can jack it up and cut the steering tot he side, then hand spin the tire to check for binding or slop or rust stains at the caps.

Could > this be a bad U-Joint? Yes, it could be a bad axle joint, but if we're not talking about full- lock turns or something close to it, I'd have to make sure you torqued the axle nut properly. > I also have another problem where the steering > wheel doesn't go back to center after turning.

Not likely on the TJ unless you've put on aftermarket hub locks, as binding axle joint (as your mechanic was thinking) only does that when it's not spinning. A binding joint will shake your wheel -- In your case, 19/20 times it's traced to binding in ball joints/steering linkage or bad alignment. Alternatively, if someone's been in your steering box lately, it might have been "adjusted" too tight. Jon IF the steering wheel returned to center before you took the hub off, then you have a serious problem that you need to address before you drive this vehicle again. In tandem, the new noise and the new behavior raise a huge red flag that tells me that the vehicle is unsafe to drive. It is possible that the UJoints are bad (either one or both of them), but they would not cause steering problems where the wheel does not come back to center. If the hub was not installed correctly, then there could be popping noises and the steering may not respond properly. I could be wrong, but my guess is that the front tire is about to fall off. > Hello everyone: > [quoted text clipped - 7 lines] > > Mike To clear a couple of things up. First of all, I bent back my dust guard on the brakes and the problem lessened. Now it hardly happens. I guess it was just everything "settling in." With that problem out of the way (I hope), I still need to address the center problem. Yes, it happened before I changed the hub, and the steering box is brand new (but it happened before that as well). I'm gonna hopefully rip the drivers side apart Saturday so I can check the U-Joint on that side. Some of you have suggested that its NOT a U-Joint. What else could it be?

The steering box was installed wrong. The pitman arm has to be removed and put back on in the right place. I suggest turning front tires so they are straight, removing the pitman arm from the steering box, turning the steering wheel straight, then putting the arm back on. It's too bad that the hubs are between you and the u-joints, you have to repeat all of the work you already did to get to the u-joints. > To clear a couple of things up.

First of all, I bent back my dust > guard on the brakes and the problem lessened. Now it hardly happens. Woah now! That is 'not' a good thing!!!! That means the hub has lateral movement in it which means either the bearing is shot or the hub is loose or the axle nut is loose. Any of these can cause the front wheel to fall off. I > guess it was just everything "settling in." That does not happen with your repair. It is either right or wrong.

A bad ball joint can or will cause the steering to bind. That happened to me recently and I had to 'pull' the steering back straight. Again this can cause your wheel to fall off when the ball joint fails. I also suspected my steering damper shock, but it turned out mine was a hollow tube with a rod flopping in it.

I'm with Mike on this. You seriously need to take the right side hub apart again and make sure it is PROPERLY installed. Everything you've said is a Red Flag screaming DANGER, ABORT. This can lead to serious death or injury to not only you but innocent bystanders. > I >> guess it was just everything "settling in."

Odds are some of them aren't. tw >> death or injury to not only you but innocent bystanders. > > Why are bystanders always innocent? Odds are some of them aren't. Indeed. If you live your life by the "you get what you deserve" guideline, there aren't any innocent bystanders. Just people waiting for their next helping of ass-kicking. :-) Craig C. > > I'm with Mike on this. You seriously need to take the right side hub >> apart again and make sure it is PROPERLY installed.

Since we can't tell the guilty bystanders from the innocent ones, my humble opinion is that the assumption of innocence just seem the right thing to do. > Since we can't tell the guilty bystanders from the innocent ones, > my humble opinion is that the assumption of innocence just seem > the right thing to do. I've been a bystander and I've been innocent but maybe not both at the same time.... ;-)  SignatureXS11E, Killing all posts from Google Groups The Usenet Improvement Project: http://blinkynet.net/comp/uip5.html ok ok you guys were right...I was wrong. The noise still occurs. I removed and repeated every step from the other day. I found no loose bolts or anything. When I put everything back together the noise still occured. I had my dad drive it while I listened, and it is definately coming from that side. Since I know the U-Joint on that side is good, I'm beginning to suspect that I have a defective part (it wasn't Mopar but rather "Valucraft"). I'm gonna rip everything apart tomorrow (for the 3rd time) and exchange the part for a new one to see if that makes a difference. Mike > ok ok you guys were right...I was wrong.

The needle bearings inside can rust out on them. Look very closely at the end caps for rust stains. You also can jack up the wheel, turn the steering to the side and hand spin the wheel looking for the noise or a bind in the u-joint. Though changing the noise by moving the dust shield implies bearing issues. Did you get that axle nut on really tight? That is all that holds the hub together.

You need to take the axleshaft out, and you may as well replace the joint since the axle is out. The joints only cost about $10, maybe $15, so you may as well do them while the front end is taken apart. Another thing to be looking for is a worn control arm and/or track bar bushing(s). This would not make a "popping" sound though, so we might be missing an obvious problem because your word choice is throwing us off. Given your description, the usual suspect is the u-joint. PS I doubt that Mopar is a better part than ValueCraft. > ok ok you guys were right...I was wrong. The noise still occurs. I > removed and repeated every step from the other day.

Then I swapped out the new hub with a more expensive one, and the problem went away. I guess China doesn't know how to make 'em.

You had a bad out of the box hub that would have failed, likely in a bad way if the bearing blew out.
