Which Pinion Seal?

[StreetDragster]

Hi All, first post to this forum, and one of the first major jobs i have tried on my landy!

I've got a 1995 5 Door Discovery 1, with the 2500cc TDi300 engine.

I'm trying to replace the rear diff pinion seal, using the excellent instructions on this site, however mine has the rover diff with the 3 bolt flange.

So far, i have seperated the prop shaft/diff, removed the insulating rubber doughnut, using a home made puller removed the spigot/dust cap thing, and tonight i'm going to remove the lock nut and flange.

However, i'm confused on which seal to use, the various different sources suggest that it could be FRC8220 or FTC5258? Looking at the guide, if possible i'd like to use FRC4586 as it looks far better than the others and should last longer.

Does anyone know if the seals are interchangeable, or if not , which one i should use?

Thanks

Matt

can not realy help with the seal only get both but 75% of the time the drive flange needs replacing so have a good look for pitting or scoring where the seal runs

I have just replaced my seal and I used FTC5258, so as my disco is a 97 and which of two seals depends on the VIN of the disco, I would say yours would use FRC8220 (early vin no's).

The pt.no FRC4586 is not listed in my disco parts catalogue.

I got my OE seal from Rimmer's for just under £10+P&P I only use genuine parts for stuff like oil seals but u can get non gen. for £3 or £4.

And if its been glued in with Loctite like mine was you'll need an angle grinder to get it off...
