I recently (4 months ago) replaced both of my rear hub assemblys on my 98 eclipse gs. I only drive the car to work and back about 5 miles a day. No pot holes or anything. Yesterday my right rear hub spindal sheared off. I looked at the spindal and there was no rust or anything. This isnt the first time this has happened. 2nd time for the right side and 1 time on the left. The bearings are completly intact and move freely. Any ideas on what could be causeing this? Took it to a dealer and they have no idea except to say that I had faulty parts.
