Topic: D35 Leak/ Cat Failed

[rubberducky]

I've got a 05 and had the carrier replaced like 10k ago. (Lost ring and Pinion) Now the right (Passenger) side is leaking oil. My question is how difficult is it to remove the shaft and replace the bearing ad seal. I know a fair amount about cars. Just have never torn into the axle. Or removed the C-clip. Do I need any special tools. or will two flat heads and a hammer work.
Then my check engine light came on. went to standard auto and the guy said it is Catalyst Failure. Anyone have this problem or have a solution. I do know however I'm one of the smart few who have 100k+ on my 4 limping squirrels.

It's easy to remove axles from the D35C -C-clipped.  You drain the diff then remove the lock pin from the differential case.  The center pin should come out.  If your careful the spider gears will stay in place.  Otherwise, just rotate them out of the housing and be sure to catch the thrust washers.  With teh center pin out, (hopefully the Jeep is on stands and the tire is already removed)  Remove the drum and push the axle shaft in.  It will move 1" inwards.  The C-clip should be exposed.  It will probably drop out.  Once that's removed you can pull the whole axle shaft out.  The bearing will be in the axle tube.

Catalyst failure - was the mechanic 100% that it was the convertor and not the downstream O2 sensor?  Nothing to do but replace the bad part.  Might want to test the O2 sensor before buying a new cat.  Unfortunately I think that the stock cat on a TJ is part of the downpipe, so it'll have to be cut off and a new one welded in - or the whole downpipe assembly replaced.

Thanks Jeffy thats what I thought, I knew the process just not if I need a special tool for the C-clip. Or a good ol-=hammer. and oldjeep your right it is a one piece. I don't ever take my jeep to a mechanic unless its something major or covered under warranty. The check engine light just came on. then I took it into standard auto and they read the code. I forgot about checking the second O2 sensor. Thanks again guys
