Howdy, just completed a massive rear chassis rail job for the DOE and it passed with flying colours. Now over the last week it has developed a loud clunk and screech noise when driving.

Firstly when I took her for a drive today i reversed out of a parking space and locked the wheel fully right to take off, as i did I got the traction control sound and tc light came on for a few seconds. It was a normal take off on concrete with no wheel spins or anything like that, weird :mad:

Anyway as i go to take off theres a clunk as I let off the clutch...

Intermittently as im driving theres a loud schreeching noise in all gears 2nd - 5th gears. After a while it goes and then comes back. Its not there all the time and only started when this clunking happened.

Later, travelling down a hill at 50mph i brake slightly and then give her throttle, and the clunk again comes from lets say the gearbox/propshaft area. Everytime I brake and accelerate theres the clunk.

I slow her down to a stop and then drive forward and backwards slowly riding the clutch. the clunk seems to come at a certain biting point of the clutch.

I crawled under and checked the front prop, no play it only moved about 1cm each way. Looked reasonably ok and all bolts were tight. Same with rear doughnut, in good condition and all bolted up.

The handbrake was on so no play in the rear prop. Should I have tested this with handbrake off and wheels chocked?

I think its definitely not the rear A frame bush as the clunk was there when i was riding the clutch inching forward slowly and it was definitely coming from the front prop or gearbox side i was guessing.

I'm at a loss to think what it could be. Anybody any ideas or point me in the right direction?
 
Sounds exactly like a UJ going. Use a lever to try to move the ends of the prop, or lift the vehicle off the ground using the axles, handbrake off so there's no pressure on the props and try the UJ's again.

It might also be worth having a close look at the front wheel hub assemblies, check the wheel bearings but I suspect it might also be a CV joint, so they might need a strip down to check properly. Again, get the wheels off the ground so any movement is more apparent.
 
I would check the front Hubs and the drive train front to back. Could check the Watts linkage, but doubtful. That is normally noticed in sideways or rocking action movement. Other things to consider, shock mounts, variuos bushes etc.
 
Quick question

I have been offered a front prop in mint condition off a 2001 td5 auto.

Will this fit on my 2001 td5 manual?

Only saw a picture but it sure looks the same.
