Hello, I have a 1999 Chevy Tahoe 4WD 5.7L 2 door. I recently had both my upper and lower ball joints replaced along with an alignment. Recently, I noticed I have an extremely shaky wheel and it feels like the front of the vehicle is just rattling. I never had this problem in the past. It seems to do it going between 30-55 mph. Also, on back country roads where they are bumpy. Never happens on the highway.
Take it back. Something isn’t right.
Check the lug nuts too before driving.
Go back and have the vehicle aligned again and make sure everything is tight. Some new ball joints can be very tight and the alignment can be thrown off a little when the ball joints loosen up with driving. Just consider the first alignment a prealignment if you will.
