Okay, 2003 Dodge Ram 1500. 4.7ltr, 2 wheel drive, rear abs only. While changing the oil today in the truck, I decided to try and figure out whaer an annoying metallic rattle is coming from, as well as a roaring sound. No luck on the rattle, and I found the roaring is from my driver's side front hub bearings. No biggie, except I need to know a couple things. The hub assembly is held on by three bolts.
1: What is the torque spec for the 3 bolts holding assembly to spindle.
2: Are the original bolts reusable, or are they torque to yield (once use only) like many newer bolts.

I'm still looking around for replacement assemblies. So far Napa has the only ones I'd trust at a decent price. Mopar/Dodge's parts website is a pain to figure out. May just go to the dealer tomorrow and get the part number. I'd prefer to put original back on (these lasted 270,000 miles) as opposed to low buck Chinese auto parts junk.

125 ft/lbs Same bolts, not TTY. 180 ft/lbs for the hub nut.

I suspect you'll have some fun extracting the hub assembly from the knuckle, hopefully not too bad being that you are well out of the Salt Belt.

Thanks Rich. Unless I'm missing something, there's no hub nut. Once you take the tire off, remove the brake caliper, and rotor, there's just 3 bolts on the back of the spindle/knuckle that hold the hub assembly on. I'm already counting on a fair amount of cussing and bleeding. :lol:
As for salt, yep, not normally a problem here. I'm 30 miles line of sight to the Gulf coast, but this truck has only been on the beach 2 times in 10 years. Actually fairly clean up in there being as it has 270,000 miles on it.

I believe this is the service manual for your truck.

As with any downloadable I provide a link to, virus check it.

Awesome Loser!!!! I had a service manual, but lost it in a HD crash, and the ram forums I'm on now think it's illegal to give out the manuals. :lol:

At least with the dealer part usually they will include the bolts if they are one time use. Not sure on the NAPA part but it may as well.

Went with the Napa brand. Timken bearings, which are decent. Has a full 36 month 60,000 mile warranty. Replaced the driver's side (was definitely bad, grinding and loose) plan to replace the passenger side next week or so. It was really easy, did it Wed afternoon in 30 minutes total. Wed evening, I had a job in South Louisiana, so drove the truck. MPG went back up to 17.5 average for the whole trip (900 miles) Still not as good as the truck used to average when it was new, but much better. Was around 15 or so.
