on highway bad vibration in front end while gets worse when excellerating, slowed down to pull over and hard to turn wheels. stopped for about 15 minutes and got back on highway was fine for about 5 minutes then got bad again. I thought drive shaft but 2

Well the problem turned out to be wheel bushings and motor mounts. Had them repaired but now its stating to do it again. It feels just like I have a flat tire but does not do it constantly. It did it the other day after driving about an hour, pulled over tires were all fine. It quit for a minute and started doing it again. I drove a couple other times with no problem but did it again today.
