I need to replace the wheel bearings in my truck. I haven't done this before and i found a few brands there were way more expensive then others. Is there Really a difference in quality in just a simple wheel bearing. And if there is what should i put in it.

 

It's really not that hard to do , I am not sure about the A.D.D. system but if you have manual hubs here's how to go about it.
Pull the tire/wheel
pull the hub dial then the gold bolt washer combo
pull the hub body
pull the caliper(hang it on the frame with a bungee cord or similar do not let brake line pull out or get hurt in any way)
bend taps flat on lock tab between two nuts so they can spin off
get a hub nut socket(rent ,borrow,buy not sure of size ask Toyota tech they can tell you) and remove first nut
pull second nut and washer
take a rubber hammer hit the rotor hub to loosen it up
wiggle the assembly till the front bearing falls into your hand
replace one nut and pull hub out until the rear seal and bearing pop out
remove nut again pull hub rotor assembly off
clean off old grease from spindle and bearings if reusing
pack bearings with clean grease
place rear bearing in place
replace new grease seal use seal driver to set seal in properly
slide assembly back on spindle
install front bearing
install washer and first nut set bearing pre load as follows
***tighten nut to washer next with a med blade straight screw driver place head between washer and hub wall it sits in move washer if it moves easy tighten nut again check washer again YOU WANT WASHER TO MOVE SIDE TO SIDE WITH A SLIGHT DRAG NOT TO LOOSE NOT TO HARD JUST A SLIGHT TO MEDIUM DRAG ON WASHER(this will make since when you are looking at it) this will preload the bearing
replace the lock tap washer and bend 2/3 taps to lock nut in place
replace outside nut tighten it down bend the remaining tabs on it lock it in place
replace gold washer and bolt to axle end
reinstall locking hub body
reinstall hub dial
reinstall tire/wheel
YOUR DONE
Sounds like a long ordeal but only takes about 1/2 hour per side.

As for bearing brands try TIMKIN or FAG both are quality

 

wrong! try Koyo (OEM toyota bearings)

Do not use anything but Koyo bearings. DO NOT under any circumstances use trail gear wheel bearings. They are chinese junk

 

cool. I'll look at all three brands of bearings. My only problem is it just started snowing like crazy so It'll have to wait a little while. What kind of price am I looking at. I've been trying to price bearings and so far they've been as cheep as 12 bucks a set to something 80. I was looking through schucks though and they don't usually have a very large quantity of brands.
