Axle Wrap???

So I've been running the rear spring TSB and a 1" block for about six months now with no problems (my truck never leaves the pavement, yet). I just put on a fiberglass tonneau cover and now I think I'm experiencing axle wrap. When I come to a complete stop the truck does a slight stutter. If I take out the 1" block and put in toytec AAL's will that fix my problem? Also, is it just me or do my leafs look flat? The TSB was done just about 6 months ago if that.

 

Those springs do look flat

 

It really surprises me since I just had the 4 leaf TSB done not too long ago

 

I heard that blocks cause axle wrap. So, I chose Toytec AAL.

I have TSB+AAL and a fiberglass cover. No axle wrap, but ride is a little stiff. I have the AAL for just a week. I hope it settles later on and will be better.

 

Yep I'm thinking of getting the Toytec AAL. I never thought I would have a problem with the block since I don't go off the pavement.
