Suggest get the front end off the ground and check for anything obvious by checking for movement from side to side or up and down; wheel bearings, ball joints, idler arm, bearings, tie rods, bushings, shocks, cross supports, etc. Usually can take the vehicle to a local shop and they will put it on the rack and give you an est. . Took the 90 to 'Wheel Works', they offer a front end inspection for $20 and provide a list of cost for parts and labor. Word of caution, they are like used car salesman and want to start replacing part then and there. Need to be firm, I told them I just wanted an estimate so I could make a decission whether or not to spend the money on a 90 vehicle. In my case, could not afford the cost of labor and decided to take the list to trusted part supplier and ordered the parts. Disassembled and found there were a couple items on the list that did not need to be replaced.
