Had same problem rotated wheels problem went away

 

If he has a stock driveshaft, those are Rzeppa joints and not replaceable (replace the entire DS instead). If he has an aftermarket DS, I'd be surprised if the dealer would repair.

 

The axle u joints were replaced and the seal on the front transfer case was also replaced at the same time. I'm going to try the tire balance first to see if that fixes the problem. If it doesn't I will take it back to the dealerto get check out.

Thanks for all the suggestions.

 

Not true anymore. Rockford driveline now makes replacement ds cv joints for 07-13 jks. This has nothing to do with op post but just thought everyone should know

 

Ah-hah, so they do! Not sure why anyone would do that: If you damage an Rzeppa joint, odds are that you have too much angle and you'll just damage another one. I guess just putting off the inevitable. More info for those so inclined ...

I had the front tires balanced today and I still have the shake. I guess its time for another visit to the stealership.

 

I may be new to this particular forum, but I am far from new to Jeeps and Jeeping. (40+yrs of experience Jeeping, Journeyman Heavy Equip Mechanic, worked in a 4x4 shop installing lifts and accessories) I have an old article on Death Wobble that I wrote years ago that was primarily TJ related, but applies to JKs as well -- http://www.blogger.com/blogger.g?blo...0;src=postname

I do not "know it all" and would never claim to, but I see the same in this forum that I have seen in others. Too much "assuming" going on.

The answers to the original post in this thread just amaze me. Not one of you asked for enough info to reply intelligently.
What do we know from the original post that would make anyone KNOW how to help?

Before I would start "helping", I would need a lot more info. Deep in the replies to this thread, some questions and answers were finally given that would help diagnose this, but even after reading the whole thing, I still have several questions that need answers before I would even begin to offer REAL HELP.

Things like: Beside front axle joints, did they do any other repairs or adjustments? Were the front tires rotated side to side? Any Alignment done? How many miles on the rig? Is it lifted... how much? Describe the shake a bit more. (is it just a vibration or a small Death Wobble)? Were the shocks, steering damper (Stabilizer), or other steering adjusted or replaced or are they all stock?

I could go on, but at least this info would be a good starting place. Anyone else think this kind of info might change your reply?
None of this was meant to disparage (put down) the help already offered, just give it some honest thought and tell me I am wrong if it will make you feel better. Like I said... I do not know it all.

PS: I would have bet a lot of money balancing your tires would do nothing. If you read the article Death Wobble, you'll find my real attitude about tire balancing in these kind of instances.

This is written way past the last post, so may not be relevant or even necessary now. But if the problem hasn't been repaired by now, I may have some additional thoughts that could help. Answer the above questions before asking for help though.

 

Jerry,

The Jeep has around 24K miles on it and it's not lifted, everything is stock.

This is what I had done for service:

-Four wheel brake service (lubricate all pivot points and sliders, remove all excess corrosion and road grime, adjust emergency brake.)
-Shaft, Axle - Replace Dana 30-Right
-Shaft, Axle - Replace Dana 30-Left
-Universal joint, front axle shaft, replace Dana 30/44-Right
-Universal joint, front axle shaft, replace Dana 30/44-Left
-Replaced 2 front differential Axle seals

The shake/Wobble seems to start around the 50 mph point, it's more of a wobble than a vibration but I would say it's mild compared to what I have seen and read about the death wobble. I can feel it in the steering wheel but it's also noticeable from the passenger seat.

Before the service I didn't have any shaking or wobble but now I do so my first thought was that it was related to the service that was just performed.

Thanks for your help.

 

Speed dependent wobbles that happen every time you reach a given speed and go away once you reach higher speeds are nearly always tire or wheel related. The source(s) could be an unbalanced tire/wheel, a bent wheel, a bad tire, a feathered or cupped tire tread, improper torque pattern when reinstalling the wheel, etc.

The first step would be to rotate the tires/wheels from front to back to see if the wobble/vibration moves or changes.

If it doesn't change, then further inspection of the front end and alignment would be necessary.

Can we look forward to you being this much of an ass on every post? Oh, btw, welcome to the forum.
