slight vibration felt at 100+ km/h

over the last little while, i was gonna lower my car, so i took the front suspension all apart, but then didnt do it, for certain $$ reasons... everything went back A-OK, so i have no real concerns about this, then i put on some new wheels, one wheel was bent a little, and had a slight wobble, i eventually put the stockers (almost brand new tires, all great shape) back on

all over my city, all the highways have been resurfaced, and sometimes i feel a little vibration in my car when travelling at highway speed, that i cant really remember before, but i have a feeling it may be from the newly paved highways.... do i somehow need an alignment (which prolly happened when the new tires got put on my stock wheels, last august)

any suggestions are greatly appreciated, its no biggie, i just dont like the idea of my car not being in 100% working order

ps. i had my suspension system checked out by a friend at a local suspension place, and everything was absolutely fine on inspection

check your tranny support and or pinion angle on the rear end. if you have the energy suspension trans mount it will changes your pinion angle and cause vibration at 100kph, I have the same prob.

thanks, that could be it, my tranny mount is crap :)

ttt, anyother help is greatly appreciated, this is annoying me :(

prolly not the tranny crossmember, it seems solid enough
