Default 1041 or 1031 to truetrac

Hi,

i got a 1041 which needs a rebuild before doing another mile with it..

Is it more intelligent to swap in a 1031 when going TrueTrac to make some money out of the 1041?

I am really baffled with alle these 1041 rebuildthreads where it is mostly a 1031 in the end :D

Whats the difference between the bearings of those two is there an ultimatively 1041 thread? i havent found one..

For economy reasons it would be better for my moneybag to just rebuild the 1041 ;)

Somewhere I have a link to a 960 teardown & reassy. of the 1041. I will see if I can find it tonight and list the link. No pics, just OEM illustrations.

I put the PowerLOK LSD in my 940 1041, but didn't touch the pinion (used a 4.10 from a lower mile NA 9 series). WELL, it turned out to be an easy find:

the 1041 (locker, that's really the big difference) chunk tends to wear out the little gears on anything really fun. The trutrac shouldn't wear out like that, AND it's not a locker so it's probably a bit better to drive.

Taking a locker apart is fairly easy, there's not much to them, note the positioning of the counterweight and governor, and the count of frictions and steels on each side. Don't set your clearances too tight.

The side bearings on the carrier (carrier bearings) are the same 1031/1041.

I'm closing in on 100k on my TT, damn thing is completely silent, fully effective though. I'm with Kenny, definitely prefer the TT over the G80, though the G80 did work reasonably well half the time.

1031 740 axles are wee bit longer and not as thick as 1041 axles. SAme size where they go into the diff, but then get thicker from there to the other end then 1031's. But they always break for me right at the spot where they go into the diff.

It's a welded diff breaks the axles just driving around and drag racing with slicks can break them but welded breaks them easier. I've broken them with G80 and slicks and drag strip and then drove home with one broke one and one wheel drive.

I broke em with 235hp/275tq and 12.61 ET.
