The rear hub on my trailblazer has stripped out twice in the last 2 months. What could cause the hubs to strip out this often? I just replaced it around a month and a half ago and it stripped out again today. Any ideas would help.

 

your talking the splines on the hub are stripped,so now its just spinning around the axle?

 

When you replace the hub put some silicon on the splines and tighten the nut good and tight.My 400 Sportsman used to strip hubs all the time until I started doing this.

 

yeah the splines are stripped so it just spins around the axle
