Front suspension torquing

[dodge68charger]

Im going to drop my engine from underneath the car with the suspension bolted together. Should i loosely bolt it together then final torque it when the full weight of the vehicle is on the suspension or will it be okay to final torque it on the ground. Thanks

I get it really close to the ride height I'm wanting using a floor jack and then tighten everything up....

Only thing that really needs to be torqued at fine height is the lower control arm at the K frame.

So, it's ok to tighten up the upper control arm bushings in full rebound position? You can do that but I won't.....

X2!

Always torque the suspension to factory spec's with full weight on wheels. If you think about it, dropping a car to full weight on wheel's from an unbound position add's at least a ton to the pressure exerted on those component's up front. Not to mention our uni-bodies are slinky's when up of the ground, so when putting back on the ground there is also added shear & tensile force. Like Cranky mentioned, as well as your Factory Service Manual mentions in several locations, torque with weight on wheels.

Good luck.

It is going to need an alignment before it can be driven very far. Top bushing will go into relaxed state at that time because of load of vehicle being on the suspension. Have you ever removed a upper ball joint and had the upper control arm hang in mid air?
