Common Torque Procedure for the Front Wheels?
 
1 Attachment(s)
Tomorrow I'm going to grease the front wheel bearings (tips on the best stuff?) and torque down the spindles.
Is there a torque spec or trick procedure...Like,

"Torque to 40ftlbs and then back off on the crown nut to the next available hole for the pin"?

Anything like that? My manual is stock. So, I wondered if there is a current "right way" to do this other than what I could find in there.
And,...since I'm asking....Do I need to "bleed" the power steering unit? It's brand new. The truck's not running yet but is up on jacks getting
ready for the front clip to go on. No steering wheel on the column yet.

I just thought, ".....Before I put the clip on, I'll do X, Y and Z...".

torqueing wheels is far overrated// look at racing they install them in a circular pattern in less than 14seconds and they're confident enough to drive them 200mph// me i've just tightened them up for the past 45+years and never had an issue

You need to preload the bearing by tightening the nut until the the bearing begins to drag, not bind, and then back off the nut to the next cotter pin hole. I do not use a torque. I believe these instructions match the service manual. I has been a while since I have pulled the hubs off.

The power steering pump and gear box will need to be bled. Once they are connected and filled, turn the steering wheel from right lock to left lock a few times to let the air out. Refill, and turn back and forth again. Repeat until the fluid level stays constant. This process is performed without the engine running...at least that is how I did it.

thats because they dont care about the abuse they put on them ,they dont care if the rotors get out of shape they change them after every race ,
i would still torque the wheels in star pattern to the proper torque with TQ wrench

Perfect info. Thanks much.

I have always spun them and torqued them down 20ft lbs, spin it, 30ft lbs, spin it then 40ftlbs. Then backed them all the way off and set them like Alex Hayley said. That seats the bearing first before you snug it up. I know it will be too late but I will see what the manual says when I get home this eve.

lol...as said above, they have been over-torqued and they same gun will be taking them off. How many of us carry an impact gun or send one with our wives when they go out? I worked for a tire store for 9 years and know the value of torquing lugs. The goal is to get the load even and tight enough to hold safely yet not so tight that they can't be removed with common tools that are in the back of most cars along with the spare. You torque "most" passenger lugs to about 80 lbs in a STAR or crisscross pattern.
