coyled Scott You are crushing the bearings in the hub housing. The XJ book said 140 lbs. You may be stretching the threads on the end of the stub axle. You could crack that hub housing, it's only Aluminium. If you are hard racing you are going to get a little play. Are your hub carriers the orignials design or from CWI? If you are going to keep racing, You should go to billet hub carriers. I would also get chromemoly stub axles, driveshafts with safety hoops, differential cover with carrier cap supports.
Rdorman Rick you want a black spacer with a L code on it from Jag the size is .1385-.1395in that should put you right on the money. Rick Lake Ps I found nothing in the Jag XJ6 book about changing the spacers. It said to check, load bearings, check play and add spacer as needed to get correct end play. Spec in the book is .002-.006in. Hope this helps
