I ran out of time on sunday.. Guess its going to be a midnight job this week.. Heading to Kal for the weekend and want the wheels aligned before I tow the camper all that way..

You'll be right mate - like baker said way back just make sure you have then torque'd correctly. I do mine up firm initially and give it a quick drive around the block before adjusting them properly - gives it a little run in.

Enjoy Kal! It's lovely this time of year (but cold)

I'm just overhauling the front suspension and putting in new drive shafts. When I took the left knuckle out I got a lot of dust of the wheel arch into the back of it... So I'll have to clean the whole thing out before putting it back in. I was thinking to put new wheel bearings in while I'm at it. Just for peace of mind. Do they normally come with all the seals needed? Does anyone have a part number for the little needle bearing?

I have manual hubs. They have a fair bit of play although nothing appears to be worn. Has anyone else noticed that with their hubs?

I would also like that part number too to the needle bearing.....

Yes the wheel bearings that I got came with seals... ask when you purchase them...
Tip.. Sparesbox on ebay has some great specials on atm... and they have Afterpay...

I have dealt with them several times and are a great mob and prices are the best I have found... that's where I got my bearings, Rotors, pads, and bits from...

I looked them up and they are $20 on Aliexpress..... They were on the car when I bought it. I might replace them with something decent. Any recommendations?
Does anyone have the automatic free wheeling hubs that you often see on cruisers?

I don't know if there are any professionals here..
According to the repair manual and the way it was on my NL, Mitsubishi has the lock nut directly on the bearing and the washer outside. The little bolts go through the lock washer into the lock nut. On Toyota, Nissan etc it is usually the other way round. The assembly (lining the holes up) is a lot easier the other way. Does anyone know why Mitsubishi decided to do it different?

I've got it all back together now with new CV shafts, uca bushes, bearings, gaskets, needle bearings, AVM hubs.
The upper control arm bushes where a hell of a job! Needed to make a few tools to get them pressed in....
Nothing I'd recommend to anyone without a well equipped workshop and a lot of experience!
For pulling out the needle bearings I recommend using a glide hammer. Worked a treat.

step by step photo's of process. I'm replacing rotors/researching re-seating outer bearings now, sharing this in kind..

yeah seeing a few comments about not needing to torque the bearings in with the lock nut wrench, which is giving me a headache trying to find something suitable. On one hand I want to make sure the bearings a seated right, on the other it's *!#$*% expensive tool for that one step.

As a Heavy Vehicle mechanic for many years the Mitsubishi front hub bearings are some of the easist to work on and most reliable assemblies I have come across.

Remove Free Wheeling Hub assembly, or the drive plate as fitted standard to Gen 2 models. And the brake caliper asemblies.

Remove the 2 screws holding the lock plate/washer on. Need a large Phillips head screwdriver. Sometimes might need an impact driver.

Using 2 large Phillips head screwdrivers, or pin punches of about 8mm diameter, poke the drivers into the 2 holes in the tensioning nut, hold them parallel then place a large screw driver or pinch bar between the Phillips heads or pin punches and rotate.

It should not be tight. Just nipped up. If it is maybe the thread is damaged or something.

Service bearings as required.

Reassemble the same as you pulled apart.

To tension bearing I just use the screw drivers in the same fashion, tightening up as tight as I can with the screw drivers in nut holes and lever to make sure everything is seated, then back off until I can feel a little bit of free play, then "nip up" until there is just a little bit of freeplay.

Fit brake caliper etc.

Fit wheel, tyre assembly so have some leverage over hub. Grab top of tyre and push, pull, in and out to guage free play. Tighten up nut until all freeplay is removed, but only just removed. Any freeplay will show up is slightly irregular wear on tyre shoulder or slight vibration through steering wheel.....sometimes. depends on tyre size, weight.

Once tension is right fit locking washer. May have to adjust the nut tension slightly to line holes up. I have found if tension is "right" backing off the nut half a hole will introduce freeplay, so I tend to tighten it up instead.

Complete reassembly. Test drive. Jack up and check freeplay to make sure there is none.

We have had in the family NAs, NBs, NCs, NJs, MKs and I even have a trailer with axle made up of Gen 2 hubs.

The Gen 1s are long gone, but never replaced front bearings. The NJ has nearly 500,000km on original bearings. Just had to replace seals a few times. The trailer is still using the bearings that where in the hubs when I bought them from wrecker 10 years ago. The MK has had the beearings replaced with second hand ones (from a wrecked vehicle we had) after mud ingress.
