Bad Shimmying between 40/45-65ish MPH
I have an outstanding thread about engine performance, but thought I'd make a new one with a shimmy I'm having.
I have a 1994 Ford Club Wagon with the 7.5L 460 V8 in it. I'm experiencing a very bad shimmying / shaking when I get between 45-65ish MPH. When I go around a bend (to the left I just noticed today) the shimmying will usually stop. Sometimes, it only shimmies for 15-20 seconds, then stops as well (same speed, going straight).
I first suspected wheel alighment, but the shop said my alignment was perfect. I then suspected tires, but got them rotated, and my shop said the tires wouldn't be having this bad effect. The shop mentioned it could be my suspension linkage is loose. I've never heard of this before, and just wanted to ask you guys what you thought about that. What type of shop can fix this, or is this something I can just jack up the car and tighten a few bolts?
Here is my alignment report:
Front Left: .4 Camber, 4.0 Caster, 0.00 Toe
Front Right: .3 Camber, 4.3 Caster, -0.04 Toe
Total toe: -0.04, Street Ahead 0.02
Back Left: 0.0 Camber, .40 Toe
Back Right: -0.1 Camber, -0.19 Toe
Total Toe: 0.21 Thrust Angle 0.30
Please advise. Thank you!
