Three problems related to axle shaft seal have been reported for the 1998 Chevrolet Silverado. The most recently reported issues are listed below.
Since purchasing this vehicle it has had the right rear axle seal replaced twice. It has just blown out again making this the third time. The last time it was replaced I was told that this part had a defective design and that they were using a "newly designed" part (seal). My cocern is that this vehicle is now out of warranty, the rear brakes will have to be replaced as well as the seal. I have also had to replace the front brakes and rotors due to premature wear after they were required to compensate for the rear brakes not functioning due to fluid contamination.
Left rear axle seal failed. Yh.
When the brake pedal was pressed the brakes made a loud noise due to leaking axle seals. The dealer has been contacted.
