could the driveshaft cause serious tranny/engine wobbling in 6th gear at 60 mph at WOT(i don't drive at WOT at 60mph in 6th gear all the time i'm using it as an example so don't flame me lol)?

I know this happens when missfiring but my mechanic said that the bolts on my U-Joint on the driveshaft were nearly coming off, i haven't got a chance to drive it yet cause he's still not done with everything, but i'm hoping this is the cause of the problem.

driving normally it's fine, but it's only when i'm driving in low rpm's

Loose u-joints = very bad. The easiest thing to do is to just tighten them up and see if that solves your problem.

could be alot of things. i'd start with the driveshaft then u joints and tie rods then tires and wheels (properly balanced)
