There just isn't enough paycheck to pay someone else to do this work. We've got to try this on our own and my hubby is so dang busy right now so I'm trying to help him out. We've got a 1990 suburban. 4x4. 140K miles. I took it in for an alignment today & the guy said he couldn't do it b/c they bearings needed to be repacked & possibly replaced. He said the tire wiggled when up on the lift. I have not had any noise or problems except vibrating when I brake. We just replaced the brake pads, but did not machine the rotors as they looked fine. I know you are supposed to, but we didn't. We have replaced the bearings on another same year suburban before, but it has been 10 years or so & we don't remember a whole lot. So my question is this. Do you think it's likely the bearings need replacing or just repacking with these symptoms. If replacement do we need the bearings, cup & cones like Napa guy said? I don't remember buying anything more than the bearings & seal last time. Also can you link me to any directions? I've been looking at the service manual & it is very unhelpful for novices like us. Lastly, does the vibrating upon braking sound like a rotor problem and which should we address first? I am NO mechanic, but I'm dang good at following directions. I've done oil pumps, starters, alternators, water pumps, brakes etc before. I would appreciate a little guidance and advice. Thanks. If there is a more appropriate forum to post this to please let me know. Newbie.
