Milesk Posted March 1, 2009 Share Posted March 1, 2009 If I remove the Diff and withdraw the propshaft from the gearbox can I replace the the gearbox seal or do I need to remove the engine again (2 times in the last 6 months ) The seal is weaping and whilst I am not loosing that much oil it is pi**%%% me off Link to comment Share on other sites More sharing options...
Paul Deslandes Posted March 1, 2009 Share Posted March 1, 2009 The only problem I can see, apart from not knowing how easy it would be to remove the diff and prop shaft, is when you remove the prop shaft, gearbox oil is really going to pour out while you change the seal. I can't think of a way around that apart from sucking the oil out of the box first by removing the top cover. TBH, by the time you've dismantled the rear end it might have been easier to remove the engine! Link to comment Share on other sites More sharing options...
Gridgway Posted March 1, 2009 Share Posted March 1, 2009 isnt removing the diff a fairly mank job anyway? Not sure it's much easier than an engine out/in. Graham Link to comment Share on other sites More sharing options...
Milesk Posted March 1, 2009 Author Share Posted March 1, 2009 Rear Diff removal is I think easier than engine out, I have a 6 speed box with drain plug at bottom so no problems there. Does the seal press in ??? Link to comment Share on other sites More sharing options...
Paul Deslandes Posted March 1, 2009 Share Posted March 1, 2009 yes it does. Might need a gentle tap with a rubber hammer/drift to seat it assuming its the same as a 5 speed. Link to comment Share on other sites More sharing options...
Gridgway Posted March 1, 2009 Share Posted March 1, 2009 I just hate taking the diff out! All those wretched washers! Graham Link to comment Share on other sites More sharing options...
Mick Day Posted March 2, 2009 Share Posted March 2, 2009 My 1996 6 speed started leaking from the rear seal almost from new. Needed a new tail housing as the bearing was faulty. Before you do anything check for radial play by moving the propshaft. Link to comment Share on other sites More sharing options...
Paul Deslandes Posted March 2, 2009 Share Posted March 2, 2009 Good point MIck, which reminded me that we did one recently where the propshaft nose splines were very worn and loose on the gearbox splined output shaft. This in turn knackered the seal. Ended up with a new propshaft although the nose could have been replaced as part of a refurb. Link to comment Share on other sites More sharing options...
