Back in 2020 I rebuilt my front suspention, used some welsh mounts. Drove the car one time, 40 miles and the put it on Jack stands in order to address rear sus...
life got in the way and the car is still on jack stands but...
I noticed chunks of black rubbery stuff lying on the floor under the car yesterday. Yep!!! The welsh mounts self destruct.
We all know that not driving a Jaguar is a bad thing. I guess that applies to those mounts as well.

They disintegrate whether you drive it or not. Contact Wayne cjd777 for replacements.

 

Having just completed this job I feel your pain. Replacing the mounts isn’t a hard job but sourcing (good) parts seems to be the real challenge. Like many users considering this repair I read all the posts and updates pertaining to the mounts that were available for years. To be honest none of our forum members had much luck or longevity with any of the parts sourced from the usual suspects. Then Wayne figured it out!

By now most members have either used or at least heard about Wayne’s (CJD777) upper strut mounts that he fabricates himself. When I was finally ready to do my mounts it was a no brainer that I would be using his mounts. What I didn’t expect was Wayne’s extensive time, knowledge and research that he put into finding just the right methods and materials. I’ll add that another member, Baxtor, was also instrumental in finding the solution as he and Wayne worked for years solving not just this a common problem but an annoying one. Did I mention that Wayne is an awesome guy? Well he is and I’m glad I got to know him better dealing with him.

Here’s a few pics for reference

 

Wayne (cjd777) and Steve (baxtor) are both top-notch guys who will devote whatever time is necessary towards helping you replace your failing front upper shock mounts with their truly innovative solutions. We are all fortunate to have them as members of this forum and I cannot recommend them highly enough....

 

The welsh mount issue was not always like that. I had welsh mounts on my car for a number of years. I only removed them in order to test my own design and the welsh were still perfectly serviceable when l removed them.
l believe the poly formulation changed at some time and seems that is when they went to ****.
Not sure what rear work you were leading up to, but l now do both front and rear poly mount kits, so if Wayne can't help, drop me a line.

 

I have already headed Andrew in in your direction for the rears,
Thanks all, happy to be able to help.
