VW Golf Mk4 2002 1.9 TDI - Transmission or Diff noise after hard stall - Sailor

Whilst fixing my previous problem rooted in a failing diesel injector loom ... I let the clutch out suddenly with medium revs and the car stationary! Causing a very hard stall! There were no sounds of anything breaking, but it was quite nasty.

I was for many weeks, driving the car with a degraded injector wiring loom, which at times caused some knocking. That is now fixed. But a new noise I think began then, and has been increasing.

SYMPTOMS: harshish "clicking" when driving at constant speed above about 45mph. This goes away, under both acceleration, and low power, wen allowing the car to slow down.

With the car on a lift, rotating the left front wheel backwards and forwards causes multiple clicks and knocks from inside the area of the diff (or the bearing on the right) in the gearbox housing. Its possible to feel these with my hand on the housing.

Also when driving and cornering turning right, there is a little noise like wheel bearings - but these were replaced <1 year ago, and the bearings feel smooth with the car lifter. Also there is a noise like a poor break disk, however they are new pads and disks from about a month ago, and seem perfect.

All these noises have developed quickly over this week, after fixing the injector wiring loom last Saturday! I'll be back on the train and bicycle tomorrow as I want to save this if I can!!!

I think the stall fatally damaged the transmission, and something has been going wrong ever since, and it is now getting really bad.

Googling it, I see that the Golf has had gearbox problems, and on Ebay, even scrap gearboxes fetch £250 or more ! and seem to be being delivered from Spain!!!!

Any advice, please again!!! I've switched engines before, however its getting to be antisocial to do major car repairs on the street! If I get a backstreet workshop to change the gearbox how big a job is it; what should it cost?

I'm not keen to give up on the car, ... the devil I know....

Look up “ crown wheel / pinion rivets “ on the VW forums .

Thankyou. I did. Some good posts there, but most about "rivet heads wearing off and a shaft wearing through the housing! And I see parts are available for changing rivets to bolts in the diff. Unfortunately I didn't see any decent videos, However there is a lot of suspicious oil around the area so I will have a search for a leak, and check the fluid level etc...

Has anyone direct experience of this? Is it easy to get the gearbox out? Are there things it could be that are easy to fix?

I watched a great video. Yes A job I can do... but not on the side of the road...

It can be done on the road, but you’ll struggle big time . 2 post lift makes the job so much easier.
