Changing the Rear End Pinion Seal

[So_Calif_Guy]

Dear List,
Several weeks ago, I saw some comments regarding the replacement of a pinion seal. At the time, I didn't know where it was, so I ignored the postings. Today, I learned where my pinion seal was and how badly it's leaking (very, but only if the differential is full! /ubbthreads/images/graemlins/grin.gif). Anyway, according to the Bently Manual, I need to remove the "Hypoid Casing" [differential] before I can replace the seal. Question - Is it possible to replace the seal with the rear end installed in the TR6, or does replacing the seal require removal from the car as recommended by Bently? Thanks in advance.

Sean,

I don't know for sure about the TR6, but it can certainly be done with a TR4. Here's an account of my experience...

Good luck!

Sean,

Hi. I'm the one who started that thread. It is possible to change out the pinion seal without removing the differential. I'm actually going to have a local shop here do the work for me in the very near future. I don't know if this is true of all TR muffler systems, but the original system has its intermediate pipes running directly below the driveshaft. Due to this the entire muffler system pretty much has to come down to gain access to the driveshaft. The shaft would then be disconnected from the front of the differential and then access can be gained to the seal. In my case I decided to replace my muffler system with a new OE one since my present muffler system is now 30 years old as the car is. The rest of the car is in such good condition that I decided that if the muffler has to come down I would replace it as well. My present muffler system is working well, it's just that it's covered with years of light rusting. To take it down and then re-install it would involve a lot of sleeving and welding due to all the pipe connections being practically rusted together and being impossible to separate correctly.
