So I was hammering, trimming and recoating the inner front fender firewall to make room for 35's, and now my cab has a slight/new vibration through the floor boards and seat. A cab shimmy/shake that progresses with speed but isn't consistent (comes and goes). And when there is more weight in the cab (passenger), the shimmy seems to go away or isnÆt as bad. <img src="/forums/images/graemlins/confused.gif" alt="" />
I trimmed the fender, and evenly hammered in the seam and that body gusset/wing all the way to the body mount.(like ErikB did) It looks good, isn't hacked or ugly looking and gave me way more clearance.
The truck is aligned, tires are balanced and I have inspected suspension and drive train for this vibe/shimmy.
I am thinking the body mount bushings shifted or ripped when I was doing the inner fender firewall hammering, which is causing the body to shimmy/shake??
Is this possible? I wouldnÆt think so, unless the bushings were already brittle and old, which they may be. I can't see the bushings inside there mounts to inspect them. All the body mount hardware is still tight and secure.
Any thoughts. I suppose it wouldn't heart to replace all the cab mount bushings anyway.
