wicked, now tell em about the diff

well, pics say more than words. looks like i've sheared the shaft which locate the spider gears

started as a rattle which i suspected was my gearbox, then started clunking pretty heavily. Called a gearbox place which said to check the diff before i throw in another box - glad i did

will be calling around some places today, the crown and pinion seem to be OK still so if i can get away with a new/used LSD centre (OEM or aftermarket), that'd be nice. otherwise same old open diff will be going in, depends on $$$ really.

[kristafa]

oh yeh, and notice how my diff oil looks glittery - i'm guessing that's not some additive to make my diff feel sexier!

[batcho101]

so thats what i can expect to do to mine once tuned lol might have to start savin to do a group buy on some 328 runnin gear

is yours a factory single spinner to?

[batcho101]

yep and its 3.45 so my gear ratios are way out at the moment first is like second gear

[batcho101]

well after a few dramas chris and i got the car running again this arvo with rebuilt diff. heres a pic of the spider gear assembly pulled apart. The shaft at the bottom is supposed to be 1 piece

[bubs]

Did yous rebuild the diff yourself or slip in another???

[bubs]

PS That cross shaft looks like the one in my air locker atm gotta fix that

[batcho101]

there where no 3.9 diffs at the wrecker so we got a 4.1 stripped it checked all bearings and seals and re assembled using the old 3.9 geas... the 4.1 gears are going in mine. the diffs are so much easy to re-assemble than a hilux

[bubs]

Did you dial guage the back lash or by hand?

Obviously you still used the 3.9 housing, so you did not have to remove the pinon and reset pinon depth.

[kristafa]

there's no adjustments in these diffs, there's a couple of cones which locate the whole hemisphere on the roller bearings, tighten them up and its centered!

seriously - i never opened a diff before, and the thing runs beautifully again

[batcho101]

yeh as chris said. the only adjustment is with shims on the 2 outside plates which centre the housing but we checked the feel and reused all the same bearings. i'm doing mine now and i'll get some good pics. honestly the easiest diff i have ever done

Okies
