what about a pic of the p38 rear.....as for water, it very easily gets in. Hot housing contracts when it is rappidly cooled by water. This effect also creates a small amount of vacuum which sucks water in. If you have ANY oil leak thats where the water will enter. The A frame ball joints are known to wear. Get a better replacement, one that is adjustable and greaseable. BTW if a Sals you need to run the correct oil as they are hypoid and create alot of heat.
