Went to get an alignment today and the shop told me it needed to replace both front U joints because the lower ball joints need replacement and that the driver tie rod end needs ot be replaced..... $811 is the estimate.
I was only getting an alignment because I cranked the T bars, There is no play in steering and everything looks normal to my untrained eye. How can I tell if the ball joints need to be replaced? I searched and saw that others who replaced their only did because of noise or vibrations. MY truck drives straight and normal.
other than a obviously torn grease boot on the ball joint, you need to check for play. Just jack up the suspect corner of the vehicle, grab the tire at the top and bottom, and gently rock it back and forth. If the ball joint is worn you will feel a slight (or severe) clunk. Doing the same thing while grabbing the tire at the sides will check your tie rod. Make sure you use a jack stand to support the vehicles weight when you do this. Don't rely on the jack alone.
