My brother has a 92 Bronco with a 302, automatic transmission, manual hubs and transfer case. I believe it has not been modified in any way. He recently had his rotors replaced by a shop and he says he is not sure if they put the hubs together correctly. He said the hubs used to click when he turned them from free to lock. Now they just move with no click. What is a good way to tell if the hubs actually lock without going offroad.

With hubs "locked", and tranfer case either in 2wd or nuetral, see if you can turn the front drive shaft. If it turns, see if one or both of the axle shaft turn. Then hold one of the axle shafts and try again to turn the front drive shaft. Just remember if you don't have a locking differential in the front, both hubs must lock in order to transfer power to a wheel. If drive shaft can't be turned, the hubs are locking and all is well.

 

Thanks. I will have him check it.

It could be that when the mechanic replaced the rotor/hub he re greased everything, and now the detent that used to give off the click when the hub lock was seated is lubed up correctly, and now you cant hear/feel the "click".

I know on mine Warn Premiums, you have to rotate the lock almost all the way around to go from FREE to LOCK, and vice versa.
