Universal joints

[JJC]

At the stage of reassembling the 6. Don't think I have ever replaced the UJs at the outer end of the half shafts. So I think I might. Question is greasable or non greasable? Any expert views? JJC

Have a good look at them under good light might find signs of grease nipples having been there..

My 4A has grease nipples on those bits. had to grind the G/gun's nozzle to get to them though.

You should always use LM grease in the UJ needle rollers prior to fitting, and ensure when pushing the cups in, a needle roller doesn't come out, as the joint might still go together, but feel very very tight.

Definitely go for greasable for long life. Suppliers offer a heavy duty version from GKN, worth the small extra cost.

As the weather is rubbish today I've been in the garage. I cannot feel any play or roughness in the UJs nor the splines. So it doesn't really make any sense to start replacing things. We're those UJs originally greasable? JJC

The joints not only get play but also the inner part of the bearing

gets mechanically destroyed on fast road TR6s and

moves from the round shape to a star, cant explain that better in English.

That results in a humming under load.

 

Also the bearing can get rid of grease and sticks but has no play.

 

So the only reliable way is to replace one after some time and as it is cheap

that is the easiest way. If the stripped bearing was still in good shape one

may be lazy and leave the other three as they are.

 

Carb cars often run out of grease, fast cars often have destroyed inner parts.
