UJ SHOT 3000S

[plasticpig72]

I thought i would adjust my handbrake ready for the French mot and i had a very nice surprise.
As the title the rightside UJ is shot away
I can also feel some play in the Wheel bearing. Luckily the UJ has circlips so can be replaced but it looks like i need to remove the drive shaft from the suspension housing.
Can i remove driveshaft and leave suspension in place.
I imagine the rear bearings are in pairs with a spacer between them to preload correctly.
I think the bearings are TR6 and UJ TR6 could someone be so kind confirm please.
Do UJ's with grease nipples exist.
Sorry about all the silly questions boys

hi Frank,
thanks it's the outer uj next to suspension housing.
It sounds like you have been there and done this job.
Maybe it's difficult to pull apart, something like removing the rear hubs on my Lotus Elan driveshafts, very tight.
Perhaps some heat can help.

It could be possible to remove complet housing with driveshaft together as an assembled unit. Replace only UJ.

well i've removed the driveshaft, very easy job. I didn't even remove the rear brake shoes.
The inner uj is o.k. but the outer uj was completely knackered. Even one of the needle bearing cups had several stress cracks and ready to fall apart. I just need to remove the hub on the driveshaft so i can replace the Wheel bearings. It's the same as on the rear hubs of my Lotus Elans so it will need a bit of gentle persuassion
I also found 4 bolts holding diff to cradle very loose

Adrian,
the rear hubs on a Lotus Elan are located on the drive shaft with a key + taper the same as my TVR. Except the key on the TVR is a square key as oposed to a cylindrical key on the Lotus Elan. Also torqued to 110 lbs/ft approx or thats's to say very tight.

yes i agree and i will change the bearings. Could you tell me the torque when tightening the new bearings with the crush spacer.
many thanks for your help Alan

There is no torque setting, this is done with a dial indicator, OR IF you build these for a living LIKE ME...THEN it's years of experience!
Adrian@

with DTI .002" endfloat, no problem. I still have Tools like that from when i worked in the Aerospace Industry.
I will see about making a Beast to remove hub and make some plate spanners for the 2 1/16" nuts.

Hub Püller availiable from "Canley Cassics" Triumph TR6. CNC machined very solid and only £67.98 incl vat or "Rimmer Bros" (more expensive but solid also)
imho it's a bargain and you have the satisfaction of doing the job yourself.
Buy a DTI (dial test indicater) from fleabay and your all set up to do a good job.

Adrian,
you are right and i stand corrected, i did not see that it is no good for TR's.
GT6,Spit, Herald 3.75" PCD and TR6 is 4.5" PCD

Richard,
what you say is logic, but i live in France and the postage for something heavy is not cheap.
As i said earlier in the blog the hub secured on the tapered driveshaft with a key is the same problem as on Lotus Elans. During the 40+ years that i have replaced the rear wheelbearings on Elans i have always used a correctly designed puller and no damage.
I have seen damaged hubs that people have butchered because they don't know what they are doing.
If i can't find a correctly designed puller to do the job i will make one myself.
For sure i would never use a three leg puller. I have the use of a press but i want to be 100% sure to support the hub without distorting it.
When i have found a solution i will post it on the forum so we can all share our TVR adventures
best regards Alan

Philpot ,
that is the Bees Knees, wow just what i need. A brillant idea. I'm sure i can buy a 3" pipe flange easily.
many thanks Alan
