Mechanic replaced ball joints and U-joints up front and unfortunately drivers side axle seal must have been damaged upon reinstall because it hasnt stopped leaking since so I figure I need to replace axle seals. I am going to go with one of the Quad 4x4 kits, but there are two that would work for my 98. QK4620-Precision machined installers to allow for adjustment of seal depths for worn axles, OR, QK4698-Precision machined depth controlled installers that stop at original depths. Truck has around 200k, so I would imagine I need the first one since my axles are worn?
