Question about the front auto hubs on GUs.

Do they bind up?

Occasionally when taking off, I get a thump noise from underneath, just like the sound you'd get if you drove over a branch on the road, also sounds like something unbinding or freeing up after being held.

I've also heard scraping noise from the front end, just like when you drag a branch underneath along the road.

I pulled over one day and the right hand side hub was noticeably warmer (not hot) than the left. I span the locking bolt in the hub around about 6 times and the noise went away.

I've heard that these hubs are strong and heard that they aren't, so have no idea. Are they known to fail or known to be darn strong? Anyone know?

Thanks for any info.
