Differential Install Order


Recommended Posts

I seem to recall reading here that there was a preferred order in which to tighten the Differential bolts, something like hanger, then driveshaft, then bottom. Is that right? I've searched, but can't seem to find it. Any help would be appreciated! I'm hoing to get my E21 LSD in today.

trans mount loose

center bearing loose

diff loose

you want all the parts (guibo, trans mount, center

d-shaft hanger) to be 'tension-free' - nothing pulling on anything

and in straight alignment

Let the rubber parts be tightened with no

load - no stress. So the rear diff ends up where the motor/gearbox/guibo/d-shaft hanger dictate. The rear diff is last to tighten

the most important point is rotating the drive shaft

and looking (and hearing squeak squeak) at the front flwx guibo


but turn in a 90 degree plane to the d-shaft. No twisting of the rubber

as it rotates. Do not tighten anyting untill you have shimmed

the trans mount, the center d-shaft hanger so the flex guibe is turning

without any twisting.

once its all aligned straight along the d-shaft from the diff to the trans

beging to tighten things up

tighten trans mount

tighten guibo

tighten center bearing with 3mm preload

tighten rear diff mounting


double check your motor mounts

and add a limit stop bracket to the passenger side

mount if your missing one

keeps the fan blade from eating yer radiator
