Two problems related to front suspension lower ball joint have been reported for the 1998 Acura RL. The most recently reported issues are listed below.
May 15, 2010. . . I had my left cv axle and tire alignment on the left side serviced. July 2, 2010 I was driving and made a left turn. About a half a mile down the road my car on the left side completely collapsed. I thought it was a tire blow out, but it wasn't. Vehicle was towed and inspected. Diagnosed: left lower ball joint caused the incident according to the service department. Currently car is in the shop as I am trying to see who's at fault in order to get assistance for the work to be done. After doing some research I found that the lower ball joint was recalled during 1996-1999 for this part. Also the left side front fender etc is dented.
A squeaking noise could be heard while driving 30 mph or less. Vehicle was taken to the dealer, who informed consumer that both lower ball joints needed to replaced.
