hi people ,

hope some one can help with this , car has been sat up for 6 months un touched , my other car died so taxed the cossie was coming back from work its fine arond 30/40 mph but soon as i bring it up on boost above 50 it feels like the o/s front wheel is trying to rip its self off ! if i back off the power it shakes like mad soon as it gets down to 60mph its fine .
now the sharfts are xr4x4 one done 1000 miles since full rebuild
front diff had a clean out and new oil 200 miles ago
has 4 brand new tires yesterday and all 4 wheels balaced up fine
no play in the front prop
lower arms are polly bushed same with arb
iv jacked it up and theres no movment in the bearing
im lost

any help would be great

thanks luke89

 

it's probably a seized caliper for starters and that has possibly warped a disc which is why it's shaking

 

Binding brake calliper? have you checked the front prop for play, or check the rubber donut on the back of the gearbox maybe

 

the prop would be second point of call and even a tiny bit of play at the front end would cause all sorts of vibrations, but the brakes would be the first port of call because it's been sat up for so long

 

I think we both typed the brakes at the same time, i would imagine thats the most likely cause

 

Car rolls fine , jack it up spin the wheel no problems
As said front prop is mint as well
Thanks for the replys tho

 

What about the engine mounts? Also what's the condition of the front tca's

Are the wheels tight and are they buckled??

 

Those longer shafts can cause problems, having said that I had the same problem for literally years, and systematically changed out everything before I finally got to changing the drivers side hub and it turned out that was the problem.

It could also be your ball joint's/suspension arm if they have some play in them.

 

The ball joints are hard to tell if there is any play on them cause of the tension of the roll bar.

 

Thanks every one car is lowered a lot and normal sharfts kill cvs in a 500 miles or less , wheels are tight and straight will swap the front to back and see if that changes , iv bit the builet and orded new tie rods new polly bush kit and new lower arms , if that dosnt fix it ill try hubs
Thanks

 

update : took it out to collect some bits front os inner cv shit its self new one ordered

 

when you put it all back together do this:

remove the strut, remove the spring, replace springless strut, fit everything back again other than the spring, then move the wheel through all the range of the strut and steering to see if it's the shaft binding somewhere

there hsould be a spring on the inner cv to push the shaft back out again and as the xr shafts are longer this may be why they were causing an issue

 

thanks dojj bought a hole new cosworth sharft should be here tusday , i will be dropping the struts out as i have new polly top mount bushs to put in ,
guess ill just wait for the parts to turn up and hope its problem fixed

 

What a pain, but I hope the replacement solves your issue! I was actually thinking about this thread the other day and forgot to mention that it could be a needle bearing from the tripod on the shaft, but that's nothing you can check unless you take the boot off and take the shaft out of the CV. Maybe the CV was just fooked
