Suspension reassembly question
When I torque the control arm bolts, is it necessary to compress the suspension by applying pressure to the underside of the control arm with a jack (in order to simulate the weight of the car)? I ask because I am experiencing some odd behavior over bumps on my 97 after installing the 1.6 differential and I tightened the control arm bolts with the suspension unloaded. I also left the chasis bracing off and the swaybar disconnected and wasnt sure if it was that, or if it was my method of reassembling the suspension.

Nope, you need to torque them when they're fully compressed, otherwise you've basically torqued the bushings down in their relaxed position. An alignment won't fix the problems that creates.
Easiest way to do this is, while the car's still up on stands, just use your jack on the bottom of the control arms and raise it until the car just begins coming off the jack stand, then tighten everything down.

Ok, wow i never realized how much of a difference that could make. I just figured that after a few miles, the bushings would twist around and not make it ride like crap. Anyway, I took some time to retorque them with the suspension jacked up and it feels like it should now.

Basically, ya thats what i did. I just jacked right under one control arm at a time, no jack stands. The other side was held up by the tire and i only lifted the tire off the ground like an inch.

how would you get to the bolts if you have the wheels on (as you would need with ramps)? the bolts I retorqued were all of the control arm bolts aside from the alignment bolts.

you need to fix all of them, including the alignment bolts. If you take it to an alignment shop obviously it will be sitting flat when they set the alignment, but be sure to tell them you need all the bolts loosed and re-tightened on the lift regardless of what your alignment is when it rolls in (if the alignment is correct they won't loosen/retighten otherwise).

You don't usually loosen your alignment bolts when you swap out the springs/shocks, though...so those should never have been touched.
Yes, I'm not sure if you'd have enough clearance or not to tighten the lower shock mount bolts, for example, with the wheels on the car and the car on ramps. Again, what I've always done is jack up the car under the wishbone, then tighten the bolts.
