Car bouncing like fun in the back seat?

**xDonny** · 01-11-2014

So at around 10-15km/h the car does this weird wobble thing, kind of like if you were to bounce up and down in the drivers seat the car would rock back and forth, or more commonly if you're doing things in the back seat. It does t again around 55km/h (but a lot faster) and then again somewhere around 90-100km/h.

I've recently done front wheel bearings, tie rods (both ends), breaks and rotors, when it does this. The steering wheel doesn't move at all and you can't feel it through the steering wheel.

Known issues: Rear passenger side makes clicking noise when you push car side to side at the back (possible strut wall or strut itself?)

anybody have any ideas?

rotate the tires back to front, see if the bound moves. if so its your tire.

while it jacked up lugs tight do all the push and pull tests to feel for any play. nothing should move back there. only thr wheel should spin.

Think it's a shifted belt in a tire? Also today might be the day to do the push/pull test as it's supposed to be 7 degrees (Celsius that is), will report back

the tire could have a lump in it, or the side wall, or just so low on tread its egging out. or the wheel is bent maybe. or loose lug nuts. wont know till you check it all out.

Mine did a side to side motion when a belt shifted/broke in my tire but that tire was on the wear bar old and cracking

good news is, tires are fine!r

bad news,

jack falls out from under car, use spare tire jack to lift car up to slide other jack back under, set under sway bar,
jack up enough to use spare jack to get other jack on the suspension, pump one more time, sway bar breaks

back to good news
getting new sway bar/inner tie rod ends

I just did my tie rod ends ~6 months ago, forgot to put plastic boots back around outside of the inner tie rod ends, now they're shot.

If you Jack up the back I use the rear crossmember thingy its near the y in the exhaust

sweet, and i also like to imagine my ps is a supercharger! hahaha.

The factory jack point was rusted so it slipped

**Scottydoggs** · 01-11-2014

yeah, dont jack on the sway bar, even if you think thats what your jacking on, its high up, no way you jacked it up on that. you'll bend stuff like that.

jack from the frame back there.

**xDonny** · 01-11-2014

It was the front end, and the jack slipped out so the brake rotor was ~ 0.25 inches off the ground, the sway bar was the highest point i could slide my jack under, broke it in the front

**Russosaur** · 01-11-2014

Oh on the front I use the subframe thing

if you have a floor jack put it over the frame bushing and jack it up. or a bottle jack also works.

the back see where the bottle jack is, just past it is the rear trailing arm, where it bolts to the under side of the cars body, theres a some frame, jack from there if the rockers are rotted out.

thanks for the info, the first pic is where i used after i picked the car up a bit with the swaybar, but unfortunately the damage was done

**Scottydoggs** · 01-11-2014

i see now front sway bar, hope the cap didnt bend on ya. if a new front end clunk starts its the sway bushing. like mine, all shot in that pic lol

**xDonny** · 01-11-2014

she didn't that's where it snapped right before it, surprisingly

**Russosaur** · 01-11-2014

Not to thread Jack but if you don't jack on the bushing can it damage it?

ive jacked right on the bolt head, and the floor jack cup fits over the bushing, no damage yet that i can see or feel. but its never gonna slide off the jack is it? thats my main reson for jack from there.
