4wd pulls to the right
when I lock the hubs in, no matter if I'm in 2 or 4wd, my truck pulls to the right. It doesn't do it when the hubs are in auto. I had the pass side hub sticking so I replaced it. My PVH is bad also,,, I finally vac'ed it down at the PVH to the front axle n it holds vacuum. Ball joints are tight along with steering. However, I haven't done the wheel bearing test with the tool it calls for (but I'm sure I could rig something up to measure the wobble). But by hand they feel good.
Could this be a prob with the front diff??
Any help would b appreciated. It rolls straight in 2wd without the hubs locked in. The 4wd works,,, just pulls Thx guys.

Typically if it pulls to one side it means only one of the hubs is engaging but since you said that the 4wd is working then the only other thing I can think of is a bad outer axle ujoint with more drag than the opposite side..

I actually haven't tried to spin them with the wheels off the ground and turned. I did replace them last year tho. But that doesn't mean they aren't bad now. By how it's pulling,, that sucker would have to be dragging hard. I did jack the front up n locked em in and they spun ok by hand. One spun the opposite way of the other. It's wierd,, there's not that many parts to mess up,, I took both sides completely down last year n put moog bj's in n new spicer axle ujoints, n also had to replace the front driveshaft cause mine was bent. I replaced the ujoints in it then went to have it balanced n it wobbled. Could the tires not having the same amount of tread on them affect it? They are the same size, n very close to the same tread depth,, but I bought them used. I don't want to spend the $$$ on fronts until I'm sure the front is tip top.

I figured if one didn't lock in, then the one that is free would do all the spinning,, thus rendering the 4wd inoperative. I am incorrect right???
It pulls to the right, n the new hub is on the right.

Unless you have a posi in the front diff if one hub isnt locking you wont have 4wd. Are you sure that 4wd is working? I would lock in both hubs and then crawl under the truck and see if you can spin the front driveshaft. If you can then one of the hubs is not locked.

Yeah that's what I thought. I do have 4wd. I actually just did 1200 miles with it locked in way up north. I have been checking the hubs at the u joint in the axle to make sure they're locked-unlocked. If one is locked, n the other isn't,, the one that isn't will spin backwards while rolling. I'm at a loss about this.

Thats normal the way it should be..open diff..
As far as the pulling something isn't right with the right side. Something may be dragging in the axle area.

One other thing could be the needle bearing in the hub. You should be able to turn
the axel with it unlocked and see if one side is harder to turn.

Wouldn't it be pulling all the time???
We was talking about the hubs last week. That would be ironic. I need to take a better look at the wheel bearing hub so I can be more informed. I did have the truck in the air n didn't notice one side harder than the other. I need to check it again. Is there no way it could be in the diff??

Ok,, So how's bout a physics question. If the truck pills to the right,, which wheel is the prob? It does it even when I'm not in the throttle. So I'm assuming that's the right wheel that's dragging. Or if it did it while I was in the throttle,, then,,, crap,,, it's still gonna be the right wheel huh? I'm thinking out loud
