shaking

are the tires a different size than the previous set? were they balanced? how are the shocks/springs? thats all i have. let me know if its none of those.

about a year ago left front tire came off i forgot to tighten the lug nuts after a brake job . the drum hit the ground and ground down some of the fins could this throw the drum out of balance .and the new tires were balaned and new air shocks in the back.

that could be the problem. The drum could of cracked or shifted when it hit the ground. Make sure nothing is cracked. The fins could have to do with holding the tire, wheel, or even the brake in place.

if this happened a year ago you would have noticed it by now.what kind of front end work did you have done,it could be that you have a bad u joint in the driveshaft,have that checked.

put new u joints on and all of the other stuff i had mentioned trying to narrow this down to the problem and thats the only thing i can think that would be left to cause the problem thanks

if you have stick transmission your fly wheel may not be centered properly causing this vibration hope this helps
