If yours is the single nut type, then do not torque to these values. It's snugged then backed off. It still sounds like yours are a bit loose.

These torques are too high, refer to the TSB i posted earlier.

Loose wheel bearings and excessive endplay are very often the cause of air gap codes. The hub/rotor are moving enough to push the wheel speed sensors out an excessive distance. This is the style of dial indicator I use for checking wheel bearings. A simple one on a magnetic base. I keep...

The old school way to do it is to tighten the inner nut to 100 ft lbs, then back it off 1/3rd of a turn, then tighten the lock nut. This gets you pretty close, but when the target is a couple thousandths of an inch, im only comfortable by confirming that with a dial indicator on a magnetic...

It's extremely important that some endplay is verified after the locknut is tightened. Tightening it reduces endplay.

That looks exactly the same. What's the suffix of your engine model (J08E- TC, TV, TA?), and the horsepower rating?

Or you can unload right on top of the transmission. Better yet, hit the driveshaft and sling it everywhere. Luckily this is a lot less common than it used to be.

Here's part of the picture.

Fingernails: permanently dirty.

I'd be speaking in tongues too if a steel bar pierced the bottom of the car and pegged me right in the butt.

I remain unconvinced.

This pretty much hits the nail on the head. Regular maintenance on the 2000 series Allison is so simple, it's ridiculous to ignore. The 3000 series is slightly more involved because it requires a ratchet and socket.

That doesn't mean the bearing adjustment is correct. No. It doesn't really matter what brand of seal you use, IMO. Endplay is measured with the brake pads pushed off of the rotor, the drive axle out (if checking the rear), and a dial indicator measuring in and out movement. Up front you're...

The stroke is around an inch. Can you post a pic of your turbo? I don't see why a Hino-sourced turbo wouldn't work. Besides, that's one less supplier to go through, I bet a new one will be cheaper through Hino. For example, Kobelco uses Hino engines on some models. An outfit running an...

You need to get the truck in the air and have the endplay on all your wheel bearings checked, and the brakes inspected. Bearing looseness or failure is often indicated by a blown wheel seal. Excessive endplay also means that the rotor is interacting with the brake pads in ways that weren't...
