P6 2000 TC 1972, ticking noise coming from flexible mounting

Hello again,

Done some useful maintenance on my P6 and a new phenomenon just occurred. I heard a ticking noise coming from underneath when the car moves back and forward. I’ve been able to visualise it but I cannot attach a movie I noticed. Hopefully the picture says enough. The big washer, bold and nut are moving vertically as I push and pull the car in the driving direction and that’s also where te ticking comes from. At first I could fasten the nut a bit what seemed to help, however now the noise is back again.

I saw something like a rubber bush in a drawing, could this be the issue, or do I have to get worried now :hmm:

Thanks,
Wilfred

That's the differential front mounting. When worn, or it goes soft, it can allow excessive vertical movement, which can allow the propshaft flange bolts to clip the cross member. Usually more noticeable when reversing because it's pushed down. Having said that, it may not be worn to excess, but the spacer may be missing between the diff extension and the mount. Whether you worry or not is up to you.;)

I’m not too worried, it looks like a solid car with only some lack of maintenance the last years. But rust can be tricky.

I noticed it recently after a 200 km drive with other Oldtimer cars, so it looks to me nothing is missing, at least I hope not.

I will try to chase this rubber part, but before that it might be better to take the old one out and see how the rest is.

cheers,
Wilfred
 
Morning,

Would replacement be doable without a ramp by the way?
I do have a proper hydraulic garage jack and solid metal support things to put underneath the car, so it would be safe, but there is not much space to do anything I’m afraid.

I also replaced the front brake pads, which wasn’t unnecessary as you can tell from the picture :). The rear pads are not so bad, to replace these would be another story..

Have a nice day,

Wilfred

If you are able to monitor brake pads easily and frequently, you can run them down to 2mm, but around there they start to break up and crumble.
 
This was a bit more than 2 mm, but I wanted to be on the safe side :).
The rear pads are thicker so they can stay a bit longer, I did have a closer look and I wonder if they can be replaced as easy as the ones on the front :hmm:

Hello,

The ticking noise issue has been solved. Luckily I could use a ramp from a local garage so the whole aria was accessible in a comfortable and safe way.

There wasn’t much material left for the bolts and nuts to keep the rubber assembly in place , this could be fixed by some welding, new washers, bolts and nuts.

So, problem solved and ready for some nice trips as long as the whether is dry ;)

Thank you all for the attention.

Wilfred
