Dave,
The only other place I can think of to leak is the pinion seal at the front=
. There=92s a chance that the old seal has worn a groove in the pinion flan=
ge, which can be remedied by a Speedi-sleeve.
When I removed the seal from my 4A IRS=92s diff, the seal material was leat=
her and it was leaking terribly.
If you are going to change the seal yourself, I would mark the position of =
the castle nut relative to the pinion input shaft, and reinstall to the sam=
e position. The nut sets the preload for the pinion bearings, and assuming =
your car uses the solid spacer removing and replacing that nut to the same =
position shouldn=92t change the preload. That=92s the best I understand it=
.

Subject: [TR] early TR4
Approx. 9600 serial number; its essentially a TR3.
The rear end leaks profusely. I understand there is/are seal(s) that need =
to be replaced; its not the diff cover gasket. BTDT
Is there a link somewhere to the process and parts needed?
Recommendations on upgrade(s)?
Thanks!
