cliff.b Posted June 19, 2022 Author Report Share Posted June 19, 2022 18 minutes ago, johny said: well yes its got to be the fit in the yoke that holds the cap stationary although I think if the cap isnt held against the end of the spider by the circlip it can move in and out (clicking sound) which wears the yoke hole.... Hmm, from looking quickly this evening there does appear to be a slight gap between the cap and the circlip so I will try fitting the slightly larger ones tomorrow and see what effect that has. If that takes up any slack, but the cap can still turn, what are the possible consequences? Link to comment Share on other sites More sharing options...
Pete Lewis Posted June 19, 2022 Report Share Posted June 19, 2022 as they are a light press fit in operation they will probably rotate without consequence but a rattling good fit is not good , couplings are available if any end float will knock/click as the caps shift they cant have any gaps or float Pete Link to comment Share on other sites More sharing options...
johny Posted June 19, 2022 Report Share Posted June 19, 2022 Yes I think in some cases they can rust/stick in place and the problem goes away or they continue to rotate and eventually the yoke has to be changed... Link to comment Share on other sites More sharing options...

So if that is the case, I either order one and change it now or run the risk that I might need to change it in the future🤔 I'm thinking that as long as I can get rid of any lateral movement I will fit it and see what happens.

johny Posted June 20, 2022 Report Share Posted June 20, 2022 I like the idea of loctite as thats exactly what its for and yes as you say there cant be much drive trying to turn the cap in the yoke. Its this last point that makes me think it must be radial movement of the cap that enlarges the yoke hole in the first place... Link to comment Share on other sites More sharing options...

Thinking about it I dont think my theory holds water as the spider might push the caps out if theres play between them and the circlip but what could push them back in again repeatedly to cause the yoke hole enlargement problem🤔 Link to comment Share on other sites More sharing options...
Pete Lewis Posted June 20, 2022 Report Share Posted June 20, 2022 with age and what ever developes the play/float/clearance is they are often well past there life expectacy and have done their bit but they dont last for ever Pete Link to comment Share on other sites More sharing options...
cliff.b Posted June 20, 2022 Author Report Share Posted June 20, 2022 Well, if the dismantling was surprisingly easy, the rebuild has been a pain, but mainly my fault. Several silly mistakes made, probably due to having too many other issues on my mind 🥺 But got there in the end and at least the UJ caps aren't moving now. Just completed a test drive with the hood up, so I could anything untoward. The original noise has gone, (although there might be a new one), nothing broke or fell off and the trunnion was just very slightly warm when I got back. I will test further tomorrow 👍 Link to comment Share on other sites More sharing options...
johny Posted June 20, 2022 Report Share Posted June 20, 2022 sounds like two steps forward😁How did you stop the cap rotating as I think I have one that does the same? Link to comment Share on other sites More sharing options...
Wagger Posted June 20, 2022 Report Share Posted June 20, 2022 There is a bit of difference between sizes of replacement bearing cups, as much as 0.002 inch. Quite a few different makes around. Loctite may do the job if really clean and do use the thicker circlips or it will wear even more. You might have to replace the yokes. In the long distant past I had parts nickel plated to take up wear. Link to comment Share on other sites More sharing options...

Yes, I had to dismantle stuff I had already done and then do it properly several times. I used the slightly thicker circlips and a loctite equivalent on the caps. If it doesn't last I will know to get a new yoke. Link to comment Share on other sites More sharing options...

johny Posted June 20, 2022 Report Share Posted June 20, 2022 I wonder if its also possible to gently squeeze the yoke in a vice to ensure the the cap is a tighter fit.... Link to comment Share on other sites More sharing options...

cliff.b Posted June 20, 2022 Author Report Share Posted June 20, 2022 I have just noticed something really strange. Ever since I've had the car it has had rather a saggy rear end but since my test drive, it appears to now be riding at least an inch or two higher and there is far less negative camber at the rear wheels. Wondering if it was something I have caused in some way but it's equal on both sides and I haven't touched the other one yet. Could it be that the car has been up on axle stands for nearly a week with no weight on the spring? Like the opposite of "settling" 🤔 Link to comment Share on other sites More sharing options...
johny Posted June 20, 2022 Report Share Posted June 20, 2022 Probably the spring leaves have stuck on each other a bit and I think it'll settle back down within a few miles... Link to comment Share on other sites More sharing options...

Yes, it does seem to go round bends well.

Might be worth trying to save the cost and effort of replacing a worn driveshaft but replacement yokes seem to be fairly inexpensive. Link to comment Share on other sites More sharing options...
