I was rotating the tires yesterday and I found that one of the four bolts,which I think hold the hub onto the rear axle, seemed pretty loose. More than hand tight but not more than 15-20 lb ft tight. It seems a little on the low side to me. This was the same side that I had the axle seal replaced so I know why its loose. The other side was around 50 lb ft so I tightened it to that. But I was wondering if anyone knew how tight the bolts should be? Thanks.
