Rear End Wobble

[LuuisHernandez]

So I recently changed out my rear end assembly and notice wobble at higher speeds. Seems like the entire rear end is being pushed from side to side. Once I left off the gas, it stops. Could it be suspension related, like the stock control arms having too much play? Or maybe an axle? Any help is appreciated. Thanks!

What year is your car? What year rearend did you install?
Did you use your OEM control arms, or were there ones on your newer rearend?

It’s a 2013 and the rear end was also off another 2013/2014. And I did use the OEM control arms.

this video shows exactly what happens to mine around 25 seconds into the video. Hope the link works.

Damn, that's sketchy as hell..... First thing I would do is go back and check all your bushings and make sure everything is tight.

Holy crap that's scary.

Yeah, but fortunately, I can avoid it by not driving in a crazy manner. It doesn’t happen every single time, but happening once is enough to raise worry.

Did you figure out what's causing this. Do you have an adjustable upper?

Not yet. Been busy with a move. May just upgrade that and my lower when I check bushings.

That's what I would do.

I am having a similar problem. Whenever i go wot the rear end pulls to the left (drivers side) so i have to let off the throttle. Seems to have only started happening after i installed the whiteline rear sway bar. I'm pretty sure i have the bar installed correctly but need to get under the car to check it again along with the bushings in my uca and lca's.

I can't tell what's worse in that video...the squeaky ass car, or the horrible music.

Well, now that the thread has been poked out of its nap . . . I wonder if the reason was found. Or if there was any mechanical reason at all and it wasn't just some combination of PHB geometric and optical illusion effects.

Not sure if I had the same issue with the car from the video, but suspension was all tight, bushings in good shape. I ended up changing tires from pirellis to nittos and haven’t had the wobble since. Soft sidewalls? I’m not sure.

What size(s) were the Pirellis and how wide are/were your rear wheels?

Tires were 305/30/20 on 11” wheels.
Just changed to a 305/35/20.
