Stub axle Replacement (Drivers)

Thanx in advance,

I've had driveline experience and can do most of it.........but...

I'm at an impass. I installed a 2.8 leveling kit on the nose of my E99 srw 4x4 and in the process had to order an adjustable track arm. (It will be here wed).
( I'm now told by the experts that if you pick up the nose more than 2 inches you will need one because every 1/2 inch of lift equals a 1/4 inch of track arm. Didn't realize that but no big deal.)

After the lift was in (looks great and really helps with a 9ft western hanging on the hook) I had the nausea of listening to my drivers hub do the woop woop at low speeds. I installed my spare hub assy but noted that the stub was scored a little (not bad) but I like everything in form so I can flush the down the road worry.

I searched and found a few helpful links but a couple seemed very off in terms of how to do this right.

I'm capable and have the necessary tools but unsure if I have to pull everything out of the diff or just pop the bearing crosses like the driveshafts.

Any help is appreciated.

I'm not against dropping it at a shop, but it's becoming a common ritual and I would like to get a handle on it. (I snow plow and tow heavy).

Thanx again,

Denny

You already know most of this but you're going to have to remove the brake caliper, hub bearing assembly and then the outer dust seal (replace with new) and then the axle will slide out. You will also need the driver tool to place in the new dust seal, you can also build one from home depot. Once the axle is out then you can puns out the axle U-joints.

The hardest part for me was uninstalling/installing the new axle U-joints. Also forgot that you are probably going to need a new inner axle dust seal as well.

Dumb Question of the Day: is the bearing that failed the one that is lubed through the ABS port?

Not sure what happened to Denny, but you have the main hub bearing where you can grease through the zerk and you have the needle bearings where the stub rides on.

That mod may help keep the bearings from wearing out?? I had a bearing go out on my 99 with no advanced warning and the LF wheel came off with a load of cars. NOT FUN!!

It won't do anything for the needle bearings as you have to pull the hub off and manually pack in grease. For the main bearing the grease zerk will help it last longer.

My loss was the needle bearings.

I lube them manually every 2 years. They just gave up with no warning other than a very small warbling sound at low speed.

My stub axle suffered a slight scoring that I sanded out with emery for the most part but it is still a little grooved. I Had a spare/used hub I installed to get me thru this snow storm but my intent is to renew both sides with new hubs and at least one stub shaft.

I appreciate everyone's help and advice.

Denny

Just rcvd my track arm from California.

Not happy. "direct fit, no other alterations....blah blah.

The ID of the ram bushings are almost one inch. You can't make sense of them in CM or SAE. Went to my parts god supper table and they said you would have to have a machine shop gauge and mill a bushing because they don't even measure out between the two ends. That's where I'll be tomorrow. Only 3 inches on the ground so far and looking at about a foot more. (SNOW guys, I plow)

What bull****.

No names. Thanx for the vent!

Denny

That sucks, but you have to adjust the track bar just for a leveling kit??? I have a 6" lift and never changed out the track bar.

I've read a lot on this and spoke to several world class shops and all concur that anything over 2 inches, it is necessary to center the axle.

As you go up, the stock length track bar pulls the whole axle assy to the drivers side slightly.
