Does anyone have the correct number for this? I bought a new Pro Line Front Wheel Hub assembly last year from Pep Boys and a paper came with it that said 118 ft-lbs for the axle nut. 14 months later the bearing is shot. I just bought another one from Napa Auto and theirs has the same 118 ft-lbs spec but when I was looking online there are other sources saying around 160. Not sure where these numbers come from but I found this same torque spec guide on a lot of websites. http://www.speedwayautoparts.com/Torque%20Specks.pdf.

Also, is there any trick to this hub? I noticed in the guide I linked to, there are a lot of cars where the axle nut tightening is like a combination lock (tighten to this spec, spin the hub to seat the bearing, loosen the axle nut, re-tighten, etc.). I do not have the manual for this so I was hoping someone out there might have one or knows what to do with this. Based on the guide I found, I'm not sure if I torqued the last hub to the wrong number or if I just got a crap hub from Pep Boys but I would like to make sure this one is done right. Any info is appreciated.

 

I would like to help you, but I need some addl info like year, model etc., usually hub bearings last a little longer. It makes all the difference in the world if the hub is made in the USA or where else. Be particular where its made and you should get better results.

 

Thanks Hanky. It is a 2004 Buick Regal LS, front wheel hub. Someone said that according to AllData 118 ft-lbs is the spec. I have seen 158 and 160 listed for this same year and model car in some torque spec books online so wasn't sure which was correct.

 

AllData specs are usually pretty reliable. By the way, you are using a new nut with the new hub, right?
With a new nut 118 ftlbs should be sufficient.
I did some checking and it seems the same hub assy is used on many different GM models. And the torque spec is more for the heavier models . After comparing the various models and the recommended torque , My belief is to use the 118 number. As you know unless the torque wrench has just been calibrated you should be just fine with a range of 118-125 ft-lbs.

 

Thanks for the info. I do not have a new nut as the auto store did not have that and I didn't want to wait till Monday to go to the dealer. It is easily accessible by removing the center cap so I can always change it after. I know they say to change it as well as the 3 smaller screws that secure the hub to the sterring knuckle but I have never done this before with any cars and never had a problem.
