Bought a 83 F350 manule lock out hubs awhile after I bought the truck I put it in 4 wheel drive and it made a clunking noise said no big deal front hubs are shot before long wheel drive quit working. Put in new hubs four wheel works again but I still have a clunking noise coming from the front end. but only when in four wheel drive. Did notice when I put new hubs on the shaft moved up and down a little don't know if this is the problem or not . Any help would be greatly apreciated. Let me say it is not a clunk clunk clunk but a clunk go alittle ways clunk go alittle ways clunk etc.

 

Check the front axle u joints.

i second u-joints

 

Disconnect the front axle and give her a try then--no clunk = you have isolated the problem.

 

I also say it's a U-joint.
That wobble in the shaft can lead to excessive wear on the hubs and burn them out quick. Pull off the spindle and replace the bearing, they are only $10 per side.

 

im haveing the same problem as described as above but along with the clunk drive clunk drive every time it clumks the front end jumps like i hit something when im in 4 wheel any ideas

 

My friend blew up his front locker, and it clunks every few feet, also the front wheels will not engage.

 

I bet one of both of the spindle bearings are hosed, probably ujoints too.

 

i just changed my 250 2 manuals u have 2 use a ring snap clip and repace u joints have fun

 

hi my name is dan and i was wondering if a bad lock out hub would make my 1992 ford f150 clunk and jump out of four wheel drive can somebody please help me because i just bought the truck and want to figure it out

 

well dan, it helps if you start a new thread, but hell anyway if its jumping out of 4wd at the t case it prolly needs rebuilt

 

no because the tcase was just rebuilt a year ago so i think it is the manual hubs on the front of it

 

well, i dont see how the hubs could do it, but hey watever.
