620 Rear End Swaying

[Radim]

Usually does it above 40, does it when i gas on/off... the rear sways and it's pretty noticeable just curious if anyone would happen to know what the problem is?

 

It has poly leaf spring bushings, fresh differential oil, and lowered 3".

Swap the tires to the front and see.

 

Have any leaves been removed?

If it has lowering blocks make sure they're tight. I've seen blocks tip over from being installed loose and the hoop nuts backed off. The more lift or lower you go with blocks, the more sway you'll get since the axle is supposed to be almost right on the springs. It may be time to start thinking about a swaybar if that's the case.

 

If you just lowered it by dearching the springs or removing leaves, that's what you get by making them softer. A sway bar or stiffer shocks might help.

Check your shocks.

^^^ agreed

 

have you had a chance jacked up and look at it yet ? :unsure:

Loose U-bolts will cause this as you come on/off the throttle.

doesn't seem to be your issue, but when I popped the clutch at 6000 rpm at a dead stop to get away from a crazy drunk that seemed to have a gun that my friend flipped off running cop pursuit tires (eagle gt +4's) after a completely badass suck you into the seat like being released from a loaded spring acceleration, my rear end swayed (like it was doing circles) 5 speed front end, auto rear end (tall gears). Hope it's just some shocks or bushings. Only you know if you've pushed your 620 to the extreme. btw still traded it for a perfect body 2 door 510 project before anything completely broke :)

Thanks guys will check all of this and report back to you guys!

 

Also, as far as shocks it's on air shocks.
