Mechanics here? Wheel bearing on Mitsub Challenger

Gotta change the front bearings on my 99 Challenger.

I've done the sealed unit type ones in front wheel drives and I've done trailer bearings, and have a bearing puller, so I feel OK about removing the brake calipers and ripping the hub off.

However I have no experence with (non - constant) 4WD front hubs so am worried I'll take stuff off and then hear a "boiiinnng" and watch springs and cogs and sh!t go all over the place.

Is it as easy as removing the centre nut and away she comes?

I believe I have to remove the inner hub - drive shaft seal first with a circlip on it (?) and that is all that googling has shown me. In fact googling has found very little.....

EDIT: BTW I have no idea what the hubs are I just know I can stick it in fourby at up to 80kph, and it has no little dial thingo for freewheel and lock like the old school 4WD's had. Just a cap over the centre like a trailer hub has.

Not my fault, I voted for the Shooters and Fishers party to stop the pinko commie w^nkrs from reducing our beach access, stifling the economy and confiscating tools from law abiding people.
Now be sensible I wanna know about my fourby which is essential for the forthcoming secret spot season

Perhaps ask this question on the Delica Club forum. There are plenty of mechanically able people there. From what I know the Delica and Challenger share a lot mechanically so you should find a decent answer there.

Not sure if there is a Challenger forum.

This might give you some ideas:

Hi.. It is very easy. Just keep pulling things apart till you get to the bearings. There are , as you say, circlips and locking screws but nothing to go "Boing..what the... ".. You will be fine.. Cheers.

This is how I replaced my damaged front wheel studs.

Remove the front wheel and place it under a low spot of the vehicle for safety.

Remove disc calliper and tie up with wire as not to damage brake line.

Remove six bolts that hold wheel hub

Remover ser clip from axle and then the hub cover.

Next remove two phillips head screws that hold the retaining washer.
These will be very tight, I used a phillips screw adapter and a hammer
As I didn’t have an impact screw driver. I had to hit them very hard several time,
after this they came out quite easily with a phillips head screw driver.

Remove the retaining washer

Now remove the nut that holds in the outer wheel bearing with two screw drivers as shown.

Remove the wheel hub and disc rotor. They are held together by these six bolts.

These will have to be separated to remove the wheel studs.

Place the disc in a vice to remove these bolts. They are very tight and this is the
easiest way. If you clamp the vice close to the centre of the hub it will close on
an unused section of the disc and leave very few marks on the disc.
You will need two 14mm sockets to loosen this bolts as they are recessed on both
sides. Once the bolts are removed use a large screw driver to pry the disc of the hub .

Once these are apart, hammer out the broken stud.


At this stage I removed another stud, by placing a nut on the thread and hitting it
out with a hammer. I took this stud to an auto parts shop and they matched it of the shelf .

Install the new stud by pushing it in by hand and tightening up the nut. If you have mag wheels the nut may not run all the way up the stud. That doesn’t matter. It will push in once you tighten the hub and disc back together.
When assembling the disc and the wheel hub make sure that the bolt holes line up, as these are a very tight fit and are very hard to move once together

Reassemble in reverse order.
You may as well check, clean and regrease the wheel bearings while you there.

I had to replace one of my wheel studs when I first bought the Delica. All I did was knock one of the studs out of the other back wheel ,take it to an auto parts store, Aussie Auto I think, and they just matched it of the shelf .
To remove the stud just –
Remove the wheel
Screw a wheel nut on one of the studs
Tap the nut with a hammer until it come free
Remove the nut and the stud will fall out.
To replace the stud
Push the stud in as best you can
Put the nut back on the stub, be careful not to push the stud back out.
Now just tighten the nut up until it pulls the stud into place
If the stud doesn’t put up tight just put the wheel back on and tighten the
nut up as usual making sure that the replaced stud nut is tight.
If you have mag wheels , use the nut that comes with the stud
to pull the stud in and replace with the right nut when your finished.
Job done.

Actually I do have the tools and if not paying somebody else to do an easy job so I can spend the difference on windsurfing gear makes me a cheapskate, so be it
New bearings $50 each - so $100 to do the front. A mechanic would charge $300+ as the bulk of the job is labour.

Apart from the fact that nearest dealers to me are an hour away, my cars don't see the inside of a dealership (or national chain like Automasters etc) EVER. Period.
The legacy of their errors with my cars in the past still leaves a bad taste for me. Like doing up an oil sump plug with a rattlegun and it would not come undone with a breaker bar with 3ft of pipe on it. New sump required.
Like leaving wheel nuts fingertight
Like bending the crap out of my bullbar mounts and bodgying it up so it looks good, and months later when under it I saw it was all on the p!ss (presumably they lowered it off the hoist and something under the front pushed it up)
Like gluing up stuff they broke and you find it a year later when it fails ........ and of course no warranty on those as how can you prove they did it?
Oh I could go on but I'll just get angrier [}:)]


And thanks for the helpful replies other peeps....... I forgot about Delica so now have the above pictorial and a scan of the workshop manual (shhh) from a Mitsi forum that may have been suggested to me
