Front end rumble... Stiff front hub
Trying to figure this out any help is appreciated.
I just got a 99.5 F350 Supercab with PSD. The truck has 55,000 km (35,000 mi) and there is a weird sound coming from the front. I think it is around the front right wheel. It seems to be kind of a repeatitive "whoomp whoomp" that gets louder at like 30 mph and then fades at 40 mph. It gets louder again around 50-65 mph. The truck had a safety and alignment before I got it and they only found a bad ball joint on the front left. New brakes all around. The truck doesn't seem to have any bounce, so I don't think it is a bad tire. Any ideas what it could be??
The front right locking hub turns but is much harder than the front left. I've checked the axle to see if it is turning with the wheel but seems to be unlocked.
Is there a way to lubricate this hub? Do you think the two are related in any way?

Could be the hub, but first I'd try rotating the tires and see if the sound follows the tire. Even if a tire balances OK, it can have a bad belt that can cause all kinds of wierd sounds and vibrations. Did you get the ball joint fixed yet?

Yes... sorry now that I read it again it isn't clear.
The ball joint had to be replaced prior to passing the safety.
Any thoughts on the stiffness of the locking hub?
