Rear end has lots of movement around corners?

TRXrider400 · January 11th, 2012, 10:36 AM

Ok, so at first this never bothered me.. but its been progressively getting worse. When i take corners, if there is even the slightest bump, the back of my car will sway pretty bad side to side. I put new shocks on the back hoping it would hide some of it, but nothing. Any ideas?

Tang Stang · January 11th, 2012, 10:40 AM

Have you checked your control arm bushings? With the car on jackstands and the rear axle hanging freely, can you move the axle side to side?

TRXrider400 · January 11th, 2012, 10:45 AM

not sure, i have noticed though when its jacked up. the driver side tire stays higher then my right side tire. when its on the ground the back sags to the left side about an inch.. i measured it, and its definitely not right

SALEEN961 · January 11th, 2012, 10:48 AM

Putting a rear swaybar on my car and locking the two lower control arms together eliminated the tail wagging session your talking about, unfortunately due to how soft the stock rubber bushings are a swaybar actually does help keep the axle centered, or at least provides some resistance to dampen the movements when the axle moves off center. New bushings will help to fix this problem and are the more correct way to do it but then your really talking about new control arms which can get pretty expensive.

TRXrider400 · January 11th, 2012, 10:54 AM

hmm.. alright, thanks a ton guys, im looking into it right now.

xtreme 2 · January 11th, 2012, 10:59 AM

yup, look at the upper and lower control arm bushings and check for tears or cracks. Also, ensure that the bolts are tight.

Do you have a sway bar yet?

TRXrider400 · January 11th, 2012, 11:17 AM

no sway bar

looking to see if i can get one off of a wreck or junkyard.

xtreme 2 · January 11th, 2012, 11:34 AM

just go to a used car lot. take a 14mm wrench and a 15mm socket...

are your back wheels on tight?....i know it sounds silly, but i've lost a wheel on the hwy due to that bump feeling and not double checking....the bump feeling lasted for a few days until it finally flew off

ReverendDexter · January 11th, 2012, 02:13 PM

While you might have something exacerbating it, the ass-waggle is inherent in the 4-link. Even when it's "tight", the rear axle can shift an inch either direction under load.

If your UCA bushings are shot you'll notice it more, but to fix it you need to either go to spherically-bushed UCAs or install a panhard bar or watt's link.

what damage was done after the wheel flew off?

Macunicorn · January 11th, 2012, 11:49 PM

I wonder if it just axle steer from the lateral movement axle. A pan hard bar can fix that.

the rear bumper needed to be heated back into shape...needed paint....i had to replace the rotor and all the studs...and after that i started getting paranoid about every little bump in the road...

hell i still am a little lol...i check my lugs at least once a week now...i know they're good, but it makes me feel better 100% knowing

Which car threw a wheel sixxer? o.O

the GT...discount tire had forgotten to tighten one down all the way i guess...they ended up paying me $300 and replacing my wheel & tire at least

xtreme 2 · January 12th, 2012, 08:45 AM

I would have gotten them to pay a lot more than that....

mustangmike! · January 12th, 2012, 12:29 PM

I have a how to put on a sway bar thread on the first page as we speak ...

94-95 V6's have them and idk what all years GT's have them... Same size though I think.

30$ and 15 mins of your time.

xtreme 2 · January 12th, 2012, 12:42 PM

size differs depending on year. Can come off a GT, Mach 1, or Cobra.

mustangmike! · January 12th, 2012, 12:54 PM

Bigger better

xtreme 2 · January 12th, 2012, 01:06 PM

Cobra is biggest, but it also has the tendency to break at the welds. Never knew why...
