FWD hub going?

FWD hub going?
When I turn the wheel all the way one way or the other and drive in a circle I hear a clunk, clunk, clunk, like when you have the hubs locked in but 4x4 not turned on at the dash switch. It sounds like it's only coming from the drivers side. I don't hear anything when I'm driving strait, only when turned all the way like I said. Thoughts?

I have a 4x4 02 7.3

Thanks

Well hear is one way to check those. Crawl under the truck with the 4x4 NOT engaged. Try and turn the axle by hand. If you can't then the hubs are stuck in 4x4. Do you have auto hubs or manual hubs? Either way you should be able to turn the axle shaft.

Thanks. I have the lock/auto hubs. I'll check that tomorrow when I'm changing the water pump that looks like it blew on the ride home this evening.

Just bought my first 02 F-350 SC 4x4 7.3 truck. Auto hubs were shot so I installed a pair of Warn hubs. Like the OP said mine makes a clunking sound in full turn when locked in but 4x4 off. My question is this normal for it to clunk in a hard wheel over turn??

[dieseldan2005]

Yes they will clunk or bind when you are turning hard. i also replaced mine with warn lockouts

Ya and also check your bearings too. but yes a locked in hub will cause the universals to clunk

Thanks for the help, I replaced the front bearings and seals already.

I checked the drive shafts and the passenger side will not turn when set to auto. Now what?

I would say that you have 3 options. You can take off the factory hubs and hit them with a rubber mallet and spray em with a good penetrating oil to try and break them loose, 2nd you could swap em with ones from a junk yard, 3rd you could replace them with warn lockouts. I did that to mine and napa had em for $180 bucks for both. Thats cheaper than anywhere online that i could find. By the way the hubs come out really easy, just one compression ring and they should slide out. If not spray those down with lube too.
