The reason I opted for this is that the Triumph 2000 part is a universal joint without any bushes and the bushes provide a bit of shock absorption. All other "new" versions of the FAM1718 seem to have question marks around them regarding the types of bolts used and their methods of securing the bolts.
So I today removed the inermediate shaft hopeing to fit the new coupling but noted that the upper UJ that is part of the intermediate shaft also needs replacing. The UJ is lumpy.
So, anyone any experience with "Steering Knuckle and Shaft - Upper - 157659". It seems it is available from Rimmers and Canleys at the moment. Are they any good or more chineese copies made of plastacine?
I believe it is early versions of teh joint that used wired bolts. Factory later ones were "crimped" to stop them undoing, but makes disassembly very tricky. And te bolts are shouldered, so not easy to find (or rather, impossible)
The rubber is the issue, new ones fail very quickly. And do check your used one carefully, as the rubber feels OK in the hand, but once fitted can feel poor. The refurb kits from Witor work well (i have done that in the past) or the alternative is to use Viton O rings that last a reasonable amount of time.
Re the upper joint, I got one from Leacy Classics a few years ago, and has been fine. I know of a friend who had trouble with the same part (supplier eludes me) but ended up returning a few before an acceptable one was delivered. So seems to be variable quality. They can benefit from a good clean out in a bath of diesel or similar, articulating the joint to clear any build up of muck/rust. Downside is it may be sloppy after.
But on a personal not, I have run my last few Triumphs on solid rack mounts and solid UJ's in the column. No feeling of harshness, but maybe I am a bit less refined!
