I know there has been a lot of discussion around poor quality aftermarket elastomer materials so I'm just adding my 2p. When I rebuilt the Mk2 subframes I bought Unipart ball joints. Cheaper alternatives were available but seemed false economy. Well six years, 1000 miles and sitting in a dehumidified garage and this is what the dust covers look like. So are "new" Unipart parts actually new, manufactured somewhere cheap, or is it all NOS stuff made when the cars were current ?. I have some spare Unipart kits so will just rob the covers from them,, might last another six years ?. All of the other parts are perfect though, knuckle joint/track rod end/CV boots etc. so perhaps it was just a bad batch.

I have had similar experience and now only use old parts either NOS BMC or the original parts off the car for rubber items like those, another one that fails is the rubber seals on top arms and radius arms, I think its just the quality of rubber parts now. Trouble is they are not always easy to change without major work. I also found some NOS driveshaft gaitors I will be using for same reason.

hope you get it sorted

Good job that Durex don't use the same suppliers! It seems that rubber is the problem - but only with car spares. If the same quality was slopped up to the UK bike restorers, they'd be busting the shops up! Norton and Triumph owners just wouldn't put up with it

I'll keep that in mind next time I'm at an autojumble.......... "'scuse me pal, any used rubbers on you ?"......... "but officer you see it's all to do with poor parts supply...... honest....."

I know that Catmint Gordon has been working on a quality alternative.

Hopefully he will be able to post some info soon.

BTW, The gaiters on my Speedwell car have perished already, I only fitted them about 3 months ago & it hasn't turned a wheel yet!

I had same with a steering rack gaiter, between fitting rack and going for the mot the new gaiter had cracked, probably same about 3 months,
Fitted some good originals I found now to be on safe side.

Interested in any quality parts being manufactured though.

This subject came up a while ago - relating to CV boots.

ISTR that Nick Rogers had a contact for Japanese made items.

Top quality but, by heck, you pay for it, at least £50 each.

When I worked, we were involve in specifying the 'bellows' between train carriages. The Chinese made ones were a tenth the cost of European made, but the quality was shocking. Import restrictions meant they weren't able to get US / European spec rubber so had to use their own sh...te. Their test data on each batch supplied was 'optimistic' to say the least.

Somerford were advertising Japanese made parts last year.

viewtopic.php?f=5&t=19798&hilit=rubber+quality

I've had a trawl through their web site and can not find anything. You could always give them a call, just hope it is one of the more polite staff members that answers.
