my rear passenger side wheel is hopping even when i accelerate moderately. this is 1 day after buying new tires with a LOT more traction. the car has 3.73's and a shift kit (so the suspension takes a pretty heavy load). the thud seems to only be comming from the passenger side. My jack is broken so i could barely fit under the car - basically the LCA's and mounts look fine, i didnt get an up close look at the torque arm tranny mount but it looks ok, so does the axle housing mount. I did notice the rear passenger side making a ticking noise when i rock the suspension. i think this is the shock absorber because i can feel the tick when i hold on to the bottom shock mount. The axle hops badly at when i accelerate fast (i stopped doing that after 2 times) and you can still feel it bump when i accelerate moderately. Im confused because there is no way the stock LCAs could be this weak or people would notice it driving off the dealer lot back in 91.... there is no clunking when i put it in drive or reverse (which makes me thing the torque arm is ok) any help would be appreciated

btw i did slam the drivers side into a curb at about 25mph which resulted in me replacing the panhard rod with a Lakewood model and replacing the axle shafts (drivers side flange was bent). The car was driving fine, no hop, before i got the new tires and the first day i got the tires (and i did drive it hard). and another thing, the rear passenger spring has a spacer in it from the previous owner

Could be somethnig else was messed in that hit . I would normally say get some reloaction brackets for teh LCA's . But it seems you may have different issues

rwdtech

but i drove the car for about 100 miles after i fixed everything and im just having this problem now after i got the new sticky tires. i'd like to avoid relocation brackets because i think they are too much work...sorry lame excuse i know. i'd gladly put on aftermarket ones that dont require modification

the sticky tires are probably causeing the axle to wrap more now . The relocation bracket are gonig to be needed. The actually change the geomatry . The LCA's just keep the same geomatry and just keep it the same moreso then stockers . really the relocation brackets aren;t that bad to put in .

rwdtech

anyone else have any opinions?

More than likely what he said.

It took a 100 miles to show up and it showed after you got more traction.

Its sticking and wrapping or your control arm bushings are shot too and with the tires its casuing the hop.

I've got LCA's with new bushings, new Panhard with new bushings, LCA relocation brackets, and lowering springs.
I get a lot of wheel hop from the pass side with my Nitto 555RII's when they are cold, and a bit less when they heat up.
I get 0 wheel hop with my Nitto 555's. all 8 of my tires are on 17x9.5" ZR1 wheels and they are 275/40/17.

so should i try to power brake it, do a burnout and see if it wraps? im scared i will shove the driveshaft into my tranny and then into my crankshaft

maybe it is the bushings. i was looking at the installation instructions for LCA relocation brackets and they say u have to remove the shock mounts among other things...i just dont want to do it. this is not going to be a track car and i dont plan on putting in a cam or 350 in it. this is basically a car i use to get to school and work; i drive it as little as possible. so Lakewood regular LCAs would be fine as long as it doesnt wrap under moderate acceleration. plus they are 89 bucks compared to 200 for relocation brackets

rwdtech

today i drove the car and did a stall test on it (ie holding the brakes firmly and tapping the gas) the axle sometimes wraps when i do this. i am hearing a squeaking noise too, but i cannot reproduce this squeaking noise when i rock the back of the car. that makes me think maybe it is the LCA bushings....help me

Get off your *** and under the damned car and find what's broken, I sure as hell can't do it from here...

If you have axle hop, something is still f'ed up. Whether it's shocks or bushings, somethings still f'ed. Wheel hop isn't caused by lca angle, so I wouldn't be looking at relocation brackets - they help poor traction(via proper lca angle). -

rwdtech

i mentioned in the first post that right now my floor jack is broken and i dont have the money for a new one yet. everything looks fine underneath...i was just wondering if you guys could give me some clues

so a bad shock could cause wheel hop?

hopefully i will find out on wednesday when i get an alignment. hopefully the techs will be more helpful because i cant find anything wrong.

Heh, Shagwell, not only did you use the "agree" smiley, but you also seem to have quoted me from another thread...

Shagwell

See if they'll let you take a look around under the car while they're doing the alignment(assuming it's going on a lift type alignment rack). Yes, shocks can cause wheel hop, but so could over stressed bushings - as in twisted sideways from the impact...a direction they weren't built to travel.

83 Crossfire TA - just realized that myself...atleast it wasn't word-for-word - just personal experience.

rwdtech

turns out it was a broken tranny mount...jesus christ theres always something wrong with this car...fox bodies are looking real nice about now

Oh no, a part under a lot of stress wore out!

rwdtech

haha yeah i know. i was only kidding about the fox body thing cause most 3rd genners hate them

ive been romping on it too much, im going to baby it from now on

btw the center bolt that goes through the tranny crossmember is too big and u will have to grind at the hole. i didnt use the washers that came with it
