MarcusF Posted December 6, 2023 Report Share Posted December 6, 2023 This corrosion and leaking grease was noted at my main service today. I have an MOT in Jan and suspect this will fail. The car is a 2005 987.1 5 speed. It looks like I will need a whole drive shaft, is this correct? Quote Link to comment Share on other sites More sharing options...
BBB Posted December 6, 2023 Report Share Posted December 6, 2023 IIRC that end of the shaft has no serviceable parts, so yes, it will ultimately need replacing. Mine is going that way, so I have an ebay find sat in my garage for when it gets too bad. In the short term you can clean the rust off and paint/treat the rust to slow the inevitable decay. 1 Quote Link to comment Share on other sites More sharing options...
½cwt Posted December 6, 2023 Report Share Posted December 6, 2023 (edited) Yes, the outboard end is built on to the shaft. A lower mileage/better condition one from a breaker is the lowest price solution, a genuine new one is lots! With a used one you can clean it up and apply more corrosion resistant paint prior to fitting. Seems to be more of these corroded and leaking driver shaft ends coming up recently. Just make sure you get the right one, 5 speed, 6 speed or tip, they are all different. Edited December 6, 2023 by ½cwt 1 Quote Link to comment Share on other sites More sharing options...

I’ll try cleaning it up and painting and watch what happens in the short/medium term! Quote Link to comment Share on other sites More sharing options...
nelmo Posted December 6, 2023 Report Share Posted December 6, 2023 Yeah mine was like that but only an advisory on the MOT. I can't imagine it would ever look worse, so I wonder if it would have ever failed? However, I had mine replaced - found on old one for £100 on eBay (£1200 from OPC!!!!) and Paul refurbished and fitted it. The REALLY annoying thing is that the same part for a 986 costs £150 new! I just don't get that as they look really similar... 1 Quote Link to comment Share on other sites More sharing options...

phazed Posted December 7, 2023 Report Share Posted December 7, 2023 I must say that when I bought my 986 and started work on the underside. I was disappointed at the amount of rust on a lot of the components. Since then I have seen the underside of many a 986 and 987 cars and I’ve been amazed that most of them have been at least as bad, if not worse! I don’t feel so bad now! By comparison my what seems much pampered 987.1 is pretty spotless underneath and will be kept that way! Quote Link to comment Share on other sites More sharing options...

Sorry, yes, that's what I meant - there aren't any aftermarket ones for the 987 - hopefully, they will come along before my other side needs doing.

phazed Posted December 7, 2023 Report Share Posted December 7, 2023 BTW, I prepared, treated the rust with Kurust and painted the metal work on the shafts in Hammerite. 1 Quote Link to comment Share on other sites More sharing options...

Metal is metal - look at the underside of an old Bentley/VW/Merc/Honda - they will all look bad. The trick is not to look 🙂 Quote Link to comment Share on other sites More sharing options...

Topside looks like a show car, (he does suffer from mild ocd mind). Always been impressed by that car. Should have kept it… Quote Link to comment Share on other sites More sharing options...

Great if it hasn't started leaking grease. If it is leaking the metal has split. Quote Link to comment Share on other sites More sharing options...

I'll probably have a go at mine too. Is it generally best to leave the grooved ring thing alone or should I try to treat that too? Quote Link to comment Share on other sites More sharing options...
phazed Posted December 8, 2023 Report Share Posted December 8, 2023 I rubbed down the metal casing, treated with rust killer and painted. Quote Link to comment Share on other sites More sharing options...

Just clean that, it is the pick up for the ABS sensor. Quote Link to comment Share on other sites More sharing options...
