Default Torque specs

Hey guys I finished working on my truck. Replaced the front hub assembly on both sides as well as new stubby axle shafts new seals thrust washer's and brakes.
Anyway in my buddies manual it says torque the 4 nuts that hold the bearing assembly to the nuckle to 55 lb/ft. That sounds low to me and I find others say it's 133 lb/ft.
Anyway he torqued them to 55 and after a decent drive I think something is loose. It's dark so I will get a look at it tomorrow. I also think I'm going to torque them to 133. Will that cause any issues?

I doubt they came loose but yes they are 133 ft lbs.

Did you loctite the install the studs into the hub?

That may be your issue. How did you tighten the studs into the new bearing? I thread one nut upside down, then thread another on top(so that the built in nut flats are meeting, tighten them against eash other, put loctit on threads going into bearing and then impact them into bearing. Take nuts off and then your good to go.

Wait did you re use the wheel bearings? I thought you installed new but reading again it doesn't sound like it

No sir everything is new. I tightened the studs by double nuts no lock tight but they are tight.
I pulled the front wheels off this morning and Re torqued the nuts to 133 ft/lbs and the lug nuts to 150 ft/lbs.
Now I have a vibration between 55-65 mph. Didn't vibrate till I Re torqued things. Not sure what the issue is now.

The bearings and studs are all new. New rotors new brake pads even the u joints and axle shafts are new. I may take the wheels off because now I have a decent vibration I didn't have yesterday. I did have the lug nuts torqued to 110 ft/lbs till I found they needed to be more so now they are 150 and now I have a vibration, kinda sounds like my tire but why do it now and not yesterday when I drove 170 miles. As soon as I got to about 50 I could feel it good.

Is the wheel hub centric? If not, you may not have it centered well enough.

My truck is a 2001 7.3 4x4 with stock wheels. I know that doesn't help but I am not sure and feel like a idiot but I don't know. Like you said it might not be centered maybe. It's raining and I have no where to go tommorow morning I'm gonna pull the wheels and see.

Not sure what to look for but I will take them off then Re install them. It's never had this vibration before and I have had the wheels off number of times. This is the first time I have torqued the wheels though which I set them at 150ft/lb.

OK I did some reading and I understand now but not sure what mine are but I will know tomorrow. Thanks for the help.

If you have stock wheels they are hub centric.
Since you just put new wheel bearing assemblies in, make sure that the lip that the wheel centers on is true.
150 ft lbs is correct torque for the lug nuts.

Pull the wheels and clean the hub surface of the wheel. Get all the white flaky stuff off the center and backside of the wheel.

No they’re not. If it’s an OE lug nut, 150ft lbs is stamped right on it.
Supposed to get a drop of oil between the captive washer and nut, then torque.

Hmm.. maybe i thought they said 160 on them. Lol.. either way. My 2000 owners manual said 150 to 165 and my 2015 owners manual says 165 ftlbs.. and correct about the oil. I use fluid film myself.

Well...... I’ve done very little wheel and tire work on the 11+.
Regardless, they aren’t supposed to just be run on with an air wrench like too many clowns do!

Lol. Very correct on the impact... usually takes the studs breaking off for those types of guys to learn.

Alright, just for grins, I did a little digging.
Our 03 Excursion’s owners manual say 150-165 ft lbs, and the lug nut is clearly stamped 150 ft lbs. My 05 dually is the same.
I have a 12 F250 in here for service. The owners manual says 165 ft lbs, and the lug nuts ARE NOT stamped with a torque spec.
All 3 owners manuals say clean, dry studs, and a drop of motor oil between the nut and washer.
So, I guess we can conclude that if a guy lubes the nut/washer, and torques them to 150-165 ft lbs he can rest easy.

There's like several very important steps to take when installing a wheel assembly. Are the lugs clean, how about the rotor surface, did you buff the corrosion from behind the wheel? Did you buff the center line? Did you draw the lugs in at a star pattern and only hand tight, did you then apply half torque yield, did you then lower so half the vehicle Weight is on the tires then full torque, for dually did you run around the block and re torque them??? For dually did you 180 the valve stems?

Bingo.

Amazing how few “tire shops” don’t clean the rotor and wheel mating surfaces.

Technically, if you look at the steel wheels on duallys, the valve stems are supposed to be lined up. If youve got one with all steelies, they have the 9th or 11th hole, depending on lug number, that the old 90s trucks had for the alignment pin.
