I am just curious to see if anyone else on here as done this job themselves and how they went about reassembling the front end.
He's correct on the first point, wrong on the second. You DO have to have the weight of the car on the suspension when you torque the control arm bolts. Failing to do so will "lock" the bushings in place with the suspension in a higher than normal position. I simply place the jack stands under the control arms when I do this, as it really isn't possible to torque the lower control arm fasteners with the car sitting on the ground.
As for the upper control arm bolts, they are splined and press into the frame brackets specifically so you DON'T have to spot weld them. If the splines were damaged when the bolts were removed then you may need to hold the heads of the bolts when torquing. These bolts do have normal hex heads for just this reason.
