[QUOTE="Darkside, post: 249554, member: 6899"] Perhaps I am reading too much into this, but I would love to see anyone drop the intake, sleeve, impeller and driveshaft. The remove the waterpump housing, rubber impeller and housing seat from the driveshaft, then drop bearing carrier from the driveshaft, disassemble the bearings, clean the inner housing, assemble and press the bearings into the carrier, add new rubber rings, place the bearing carrier back on the driveshaft, install the water pump and gaskets and assemble the rest of the jet pump in 5 minutes. It must be some kind of magic shop it took me longer than 5 min to write this post. Having done this 3X in a garage w/and w/out a press - one came apart very easy, the other not so much and the first I ever did was a seized bearing - that was a gem to disassemble. All joking aside, if you have a shop that will do this for the 20-50% mark-up on the bearing kit that is fantastic. That's one great shop. While you're are at it, add a new waterpump impeller (honestly not extra time once you have it disasembled. A good shop will likely sharpen and shim adjust the impeller to the liner, look for wear and check the alignment of the reverse/throttle gate - [/QUOTE]
