thomasw Posted September 24, 2011 Report Share Posted September 24, 2011 Wow. Thanks Hussein!So what happened to this coupling? I'm guessing they aren't meant to be solid with black crud like that and those little tabs are individual wet clutch type disks. Link to comment Share on other sites More sharing options...
lookforjoe Posted September 24, 2011 Author Report Share Posted September 24, 2011 Wow. Thanks Hussein!So what happened to this coupling? I'm guessing they aren't meant to be solid with black crud like that and those little tabs are individual wet clutch type disks.Half the discs are connected to the front shaft, the other half are tied to the rear section (alternating) - there was a silicone base fluid in there, as the discs slip the fluid heats up & progressively locks the discs together, transferring power to the rear. The failure of this unit was the freewheel mechanism - one of the bearings let loose from it's ramp, and rattled around like a tin can. No way to fix them.

Matt01 Posted November 13, 2011 Report Share Posted November 13, 2011 is there any way to change the center bearing of the driveshaft as viewed in the picture with the 3 driveshafts.. even vadis has no part number, and mines worn out due to a "temp fix" that ive been running for a year..

I think I'd just go reman from coloradodriveshaft at that point - the carrier w/bearing is a couple hundred...... Link to comment Share on other sites More sharing options...
Matt01 Posted November 14, 2011 Report Share Posted November 14, 2011 its more the rubber that i need. can that be changed, if i have to rebuild, i'll just wait for the CV joint to break and do it all at once. Link to comment Share on other sites More sharing options...

Matt01 Posted November 14, 2011 Report Share Posted November 14, 2011 the CV joint would have to be removed for that to be replaced aswell. yaay for AWD! Link to comment Share on other sites More sharing options...

lookforjoe Posted December 3, 2011 Author Report Share Posted December 3, 2011 ^ Thanks. Just trying to help anyone looking for differences when sourcing parts or contemplating a manual conversion Right Axle Variants '98-00'98-'00 front to back. Arrow indicates seal seat (28mm OD).So, the '00 axle doesn't work in an M66 AWD because it's too short. Fixed point is the bearing, since that is located on the engine in the same location regardless of transmission. This is from a 5 speed Auto AWD ®. If there were any 4 speed Auto AWD in '00, I would expect that it would work as is. The '99 axle will work, but the outer BG seal seat is not in the correct location.Either a .5mm collar needs to be fabricated for the seal to seat (1mm difference in OD between seal seat & rest of shaft), or a smaller ID (27mm) seal would need to be sourced. Probably easier to look for a seal, IMO28mm ID38mm ODShaft OD 27mm Link to comment Share on other sites More sharing options...
andyb5 Posted December 6, 2011 Report Share Posted December 6, 2011 Do you have an axle from a 00 AWD or XC to compare to the 00 R axle? Those still retained the 4 speed auto's, the only AWD model to get the 5 speed was the 00 R.Also, this is a great thread, thanks for organizing all this info!

andyb5 Posted December 6, 2011 Report Share Posted December 6, 2011 Hm interesting. The "model specifications" list on SS says 00 XCs still had the 4 speed, but it appears that that listing is mistaken. Looking at all the 00 XCs for sale right now, they all have 5 speed auto transmissions. Link to comment Share on other sites More sharing options...
lookforjoe Posted December 6, 2011 Author Report Share Posted December 6, 2011 Just checked further, the The original part number for '00 5 speed AWD axle is 9463921. This number supercedes to this exchange # 8251521 (8601580), so perhaps the 8251523 (8601589) is for the 4 speed. All speculation, without an axle to compare Link to comment Share on other sites More sharing options...
