Don C. Don the only thing you will have to recheck with the new bearings on the hub will be the shaft play in the bearing. Wiggle room. You may have to get a new spacers for this. I did the same repair on my Jag rearend and ended up taking the hubs up to Doug at ERA to get the correct spacers for the shafts. Too tight and you over load the bearings, too loose and you have wondering and knocking of the car in the rearend. Make sure you have the torque specs for this. The Jag XJ-6 repair manual has a good info section of rebuilding there rearend and showing how to get the correct shaft play. You can get the spacers from ERA unless you can find an old Jag dealer in the area that sells the spacers. Problem is they come in packages of 10 and you have to buy them all. ERA just sells you what you need.
Does you hubs have grease fittings? I give mine a couple of good shots after every race meet I go to. Use Hitemp grease from
Amsoil on the housings. Works great and the grease stays soft and takes alot longer to dry out. I also use this on my trailers. Over 100K between car hauler and 5th wheels my parents owned. no bearing failures. Don't over tighten the nut pass spec in the hub. Go less than more to get the cotter pin into the hole. Remember that there is alot of heat there and expandsion rate will take up the lower torque reading back to spec numbers. After replacing the bearings, ( you might want to do both sides together, Road test the car for about 10-15 miles and recheck the fastener for tightness and play. Doug has the GIFT at ERA and does it by sight and feel. 10 years and the rearend play for shafts is still tight. Rick L.
