MikeMolloy Posted August 3, 2018 Share Posted August 3, 2018 I have recently set about recommissioning my car after entirely too many years sat on jacks in the garage gathering dust. A new fuel pump got it running, and the MOT man (a fellow Caterham owner) was lenient regarding the new emissions rules (bike engine = no cat, which should be a fail according the the rules as I read them...)However, I went for a decent blat yesterday and when I got home noted the inside of the nearside rear wheel rim was coated in black goop. A bit of effort with my brutal Machine Mart mains powered impact wrench had the hub nut off and the disc removed. The wheel bearing looked OK, but the grease is light brown colour, so not the culprit. The CV boot is completely intact, so it looks like the CV grease is getting hot and seeping out of the joint where the can is peened over the splined shaft.Once upon a time you used to be able to buy a repair kit (Ford P/N 1058427) which looked like this:http://i189.photobucket.com/albums/z282/adrianthorp/photobucket-5701-1369128225774_zps0619cd79.jpgApparently this part is now obsolete and unobtainable!As far as I am aware the shaft and CV joints (or "Tripoid joints if you prefer) are all fine, so I don't want to fork out 300 quid for a new shaft from Caterham (currently listed as "not in stock" anyway.Can anyone help please? Are there any local specialists (Midlands) you can recommend to replace whatever seals are needed to stop the grease slick?Thanks! Link to comment Share on other sites More sharing options...
Wrightpayne Posted August 3, 2018 Share Posted August 3, 2018 Sure you can get streachy pvc boots that use a cone and lube to get them on or split boots you superglue.Discussed in the archives.regardsIan Link to comment Share on other sites More sharing options...

Area Representative Richard Price Posted August 4, 2018 Area Representative Share Posted August 4, 2018 Mike,Are there any signs of damage on the outside of the can?Unless it has been replaced before, and refitted without the O ring under the edge of the can, I think it's very unlikely to the the can seal leaking.I had one that had rubbed on something ('can't remember what) and made a pin hole in the can. I seem to remember that I wrapped it with pvc tape, and remained in use for several years more.Likewise, I've also seen a tiny pin hole give splatters as you describe.I'd very carefully examine the boot again.If split, replace with a Duraboot.

MikeMolloy Posted August 4, 2018 Author Share Posted August 4, 2018 Thanks for the info guys! Must admit I'm having trouble with the latest incarnation of the Blatchat search engine...Ian - sounds like you have good experience taking the CV cans apart. If you have photos of the innards I'd be very interested to see them! Will PM you with my email address.Richard - The can section is quite long before the boot clamp, and there was absolutely no evidence of the grease in that area. It was all stuffed in the De Dion ear - see photo.I think I might try sealing the can-to-hub interface with some sort of adhesive and see if that keeps it under control.Now, how do I achieve 200 lb ft????

Area Representative Richard Price Posted August 4, 2018 Area Representative Share Posted August 4, 2018 That's odd. it does look very much like CV grease. I would be surprised if it was heat that made it leak.i'd pull the drive shaft out, clean it up, and inspect further.the drive shaft should easily pull out of the diff, and you should not loose any oil.

Dave7vx Posted August 4, 2018 Share Posted August 4, 2018 It’s almost certain to be the can leaking cv grease where it’s peened over. Pull the drive shat out of the diff, clean it all up with brake cleaner, try and improve the sealing joint by peening with light hammer, clean it all up again and run a bead of silicone sealant around the joint. Probably a 90% chance of success, worse case is you have to repeat in few months Link to comment Share on other sites More sharing options...
MikeMolloy Posted August 4, 2018 Author Share Posted August 4, 2018 Driveshaft is out and in the bench vice. I cleaned off all the gunk with brake cleaner, but under close inspection with a big magnifying glass you can still see the black goop seeping through the joint.Until I can find a proper solution (i.e. if it is possible to get a replacement can, and find a rebuild specialist) I have filled the lip of the can with JB weld.Admit I am ashamed at bodging it, but guess we'll see how long that lasts!Thanks for all the advice chaps.

Wrightpayne Posted August 4, 2018 Share Posted August 4, 2018 Perhaps try redline for a boot kit which comes with a new o ring as well as the can.Ian Link to comment Share on other sites More sharing options...
