Front Nut torque

[azcummins]

Well I got my front nut that holds the rotor to the axle today from the stealer. They said they didn't have it but when I called back and talked to another guy, they had 6 of 'em for 1/2 the price!



I need to know the torque specs for the bolt though so it doesn't fall out again. Thanks guys.

The torque settings I got from the dealer were 185fp for the front axle nuts.



Didn't it have a carter pin in it?

Maximus-

I'm talking about the 4 nuts behind the wheel that hold the rotor to the axle housing. You're thinking about the nut in the center of the rotor that does have a cotter pin. Thanks for that spec though: I needed that too!

 

[Maximus]

I got 3 different specs on those. 50fp from one location, 85 from a dealer, and 90 from another dealer.



I torqued my to 100 just to be safe.

Hey azcummins,



When you sell that truck of yers, I wana buy it. You seem to take pretty good care of it, torquen' everthing to specs-n-all. I torque two things on my truck, the wheels and the HEAD, everything else just get's tightend.



Later ,Rob

I've never seen a spec given for the rotor hub bolts. Manual just says to tighten securely. 50 ft/lbs would be about right. You should use Loc-Tite 242 (blue) on them.

Rob-

You can buy the truck, but I'll have to charge you extra for the surgery on my shoulder from torquing all those bolts!



Thanks for your help guys, I'm going to buy some loc-tite today.

When I took out the bolts they where way tighter than 50fp. I would guess it took about 150fp to get them loose. I had to put a breaker bar on them to loosen them.



I have been warned, "if you don't get them tight enough you will garbage the hubs"



A brake shop I talked to said they put an impact hammer on them to tighten them. That would make me think they tighten them to over 100fp.



I plan on a re-torque this weekend on those bolts since I tightened them last weekend. If I had put lock-tight on them I wouldn't be able to do that!



Thats my 2cents!



Good luck AZ

Maximus, it probably took 150 ft/lbs to break them loose because they had loc-tite. Shouldn't need to retorque with loc-tite. 100 ft/lbs seems awfully high for a bolt that size. Just my 2¢ also

97 Service Manual says 170 ft lbs for the Axle nut and 125 ft lbs for Hub to Knuckle bolts. (The 4-12 point bolts)

 

[Maximus]

There was no loc-tite on them. I cleaned everything before I put it back together. I would have noticed.



I have been planning on purchasing a Dodge Service Manaual about $110 after shipping and tax. I really need to get one!

ata-

Thanks for the info. I'm going to crawl under there and torque them down once it stops raining.



TDR rules!
