drive shaft and shimmy issue
i have a 2003 dodge ram 1500 crew cab 2 wheel drive,5.7 hemi that was lowered and has only 1 drive shaft. i had someone change the u joints and i think he may have put it together backwards is there anyway i can find out if its right or wrong, and i also changed all the shocks and the truck has sat for 2 months and i took it out for a drive and when i hit 50 mph got a big shimmy and not sure why.
