I would bet a damaged tie rod or control arm. Possibly a damaged alignment bolt(s) attaching the lower arm to the subframe. There is a lot more force in that hit than you think. I would also check the hub for play, you may have damaged the bearings.
The burning rubber, I would check all the coolant hoses, which may be contacting a moving part or the exhaust manifold. Other possibility is the tire contacting the crumpled fender.
