I have a question about bearings in the front of my truck. would any of you know if in order to change the bearings in a 2WD, would you have to change the hub, or could you just change the bearings?

 

what year is your truck?

 

its a 2008

 

i think 2wd rangers have seperate front bearings...i know 4wds are sealed units but not too sure about the 2wds

 

yeah same here, I have been trying to figure it out, and the weather is the pits over here, so i dont feel like working in the driveway to figure it out that way

 

So i asked the parts guru at the local dealership told me it was an inner and outer bearing

 

well thats not too bad then

 

Yes, the front of a 2wd has a set of inner and outer bearings. Both have the outer races pressed into the single piece rotor/hub. Replacement 2wd rotors usually come with new races in place. The total stack goes knuckle/spindle, inner seal, inner (larger) bearing, hub/rotor (w/ outer races), outer (smaller) bearing, washer (keyed to flat spots on spindle), lock nut, castled lock nut retainer, cotter pin, dust cap.

The inner seal fits into the rotor/hub, but can be applied with a hammer and length of wood and removed with a screwdriver. Expect to replace the seal when servicing the bearings.

The lock nut has a specific torque procedure: ~20 ft-lbs while spinning the rotor in one direction, back off 1/2 turn, ~16 in-lbs (NOT FT-LBS, think greasy finger tight) while spinning rotor in the other direction.

The cotter pin and dust cap can be reused a couple times, but have a set on hand in case they get damaged. The washer, nut, and retainer castle almost never go bad.

Advice on repacking (replacing the grease) bearings varies. I hit mine around every year or so. Definitely do it if you go spindle/axle deep into something (mud, water, etc.). The bearings typically get replaced with the rotor/hub on a full brake job or if they are damaged.

 

thanks for the heads up, very helpful post Jason, thanks.
