Help needed.. Rear suspension torques.

Hi Guys.

I need some help. If one of you has the FSM, could you please tell me the torques for the rear wheel suspension assembly.

I need following.
-Rear wheel bearing bolts.
-Shock absorber bolt.
-Camber and suspension rod arm bolts and ball joint.
-Rear caliper bolts.
-Drive shaft U-joint lash cap bolts.¨
-Spindle nuts.

Hope you can help.

we need a little help here. at this point, we can only assume it's a C4. I don't know if the subject torque values are the same across all years, and if I was betting man, i'd say they're not. so having said that, what year?

From a '96 FSM but they should be good for your '94

The '96 FSM seems (TO ME) to have some brake spec issues (for the rear) so these are from a '90

Bracket mounting bolt: 70 lbs.ft (95 N*m)

U joint straps (depends where you look prop shaft or rear axle)

From rear axle: 17 lbs.ft (24 N*m) From prop shaft: 18 lbs.ft (24 N*m) *these are pinion straps

SIDE YOKES @ diff & wheel: 26 lbs.ft (35 N*m)

OK, I can't figure this out - how did you know the OP has a 94? I looked at his profile - nothing. there is a small pic in his album, but I can't tell anything other than it could be a 91-96.

I don't check profiles but if I recognize the "user ID" I might recall the thread I last saw (in this case I recalled) OR I just search the C4 section for posts by the "user ID" which generally reveals some information.

His recent post:

BTW OP - what did you find after closer inspection of the D44?

The FSM misinformation in the '96 is that the front caliper bracket torque specs seem to be repeated in the "rear disc brake section" - '94 specs are the same as my reference to the '90 caliper bracket bolts I'm sure.
