Diff Seal

[TVRleigh_BBWR]

We have the rear end apart again due to bearing, see other post.
we have a slight weep from the diff behind the disk, can these be changed with the diff in place.

I think it can Leigh but dont quote me on that.
Im sure some on told me you can but if you have the back end apart like me why not take the diff out totaly and give it an overhall

Tempting but only place I've seen that service them charge about £500, plus it's quite easy to get things wrong with a DIY overhaul

I've just had my diff rebuilt due to the bearings but I had mine completely overhauled. When I dropped mine off the engineer pulled out both outboard bearings which came out after removing the six nuts that hold them into the main diff. I can see no problem getting the side housings out with the diff in the car, except they may not have enough clearance to go through the chassis tubes. They still need setting up when rebuilt as they use crush collars to set the preload which precludes just taking the drive plates off the end and then replacing the oil seals. I guess you would be able to see if there is room to withdraw the housing through the chassis tubes with the discs off. Sorry I can't give you a definite answer as I dropped my diff with the discs and brakes on.

Where did you take it and how much did they charge, as may take my spare and then swap them

Any good gearbox place should be able to do it. I took mine to South East transmissions in Folkestone and the total with the dreaded was just shy of £500 that included all bearings and seals, mines a keeper so hopefully will not need to do it again.

Leigh,

If you wish to OH seals with the diff in situ :-
The flange on the diff behind the drive shaft coupling unbolts, and the bearing/seal assembly can be removed with the diff in place.
As usual with TVRs access is not always easy.
