Timken 515020 front hub unit install question

About to install a TIMKEN #515020 front wheel bearing hub on my 02 7.3 4x4. Should light grease be used when installing the o-ring to help it seal or does it go on dry?

Thanks.

As long as all the surface areas are clean, I wiped my inner down with brake cleaner, then a wipe down with WD-40. It should slide in and seat without any issues - then torque the hub down to the knuckle

Going together is one thing... coming apart in 5 years after they went together clean, and all that clean metal rusted, diffrent story. I'd grease them, not thick, just a coating, so when you replace the next one, it comes apart easy. Just my 2 cents...

Are the needle bearings pre-greased from TIMKEN also?

Yes, you should not have to pre-grease anything.

I just ordered a set of timken wheel bearings for my truck to.
Does anybody the torque for the studs holding the hub assembly to the axle?

Keep in mind - those are 'studs'.
Just run them in - and another 1/4 turn (and no more.)
All your clamping force will be by the nuts which you torque on.

Yeah, I realize they are studs. I guess the proper question to ask would be whats the torque for the nuts!
