Axle hop

They shouldn't have moved if torqued properly. Make sure, and I can't emphasize that enough, that they use very liberal amounts of anti-size compound coating those sleeves on your drives. Or you will regret the day you ever had them installed because they will seize on there and be a Mo-Fo to get off if they don't. I wouldn't even have them on there myself if I wasn't the only one doing tire work.

 

Appreciate the update!

probably not your problem, but worth adding to this thread

 

Did you ever get this straighten out? I'm having about the same problem on my w900... Same suspension

 

I know this is an old old OOOOLD post but I have the exact same wheel hop you mentioned in a 2013 volvo 780 with the d13 and ishift trans. Were you ever able to ultimately and finally cure the issue you had? I think in my case I probably do have off centered wheels. One tire shop said I had runout, went to another shop and they couldn't see anything wrong with the tire. Sometimes it will smooth out and have a little like an oscillating vibration, but #### man it's difficult getting it to a speed it isn't doing that junk.
