Need Jag IRS help

Well, I just checked my left rear wheel, and I've got a bent hub flange. I measured 0.003" radial runout and 0.008" axial runout, at the outer edge of the wheel hub flange (just outside the lug studs). It is enough that you can see a slight wheel wobble while following the car.
This is a standard 1988 XJ6 hub/wheel flange assembly. Anyone replaced one of these? Is this something reasonably do-able or should I take it to a Jag mechanic?
I read the Jag manual and it looks do-able except for pressing on the bearing races, but there is a mention of setting the free play also. The best price I found for a hub flange is $189.90 ($211 list) at Moonlight Mechanic...ouch!
Thanks.

Ken: I just replaced an inner bearing on my car a month ago. It was not a problem. I did go to the jag dealership and had the bearing pressed. the cost was 100.00 for the labor.

As far as the freeplay, there will be a spacer between the bearing
and the shaft. You should be ok. I was. The freeplay is 2 to 4
thousands. Your locking nut need to be tourqued to 100 ft lbs.

Good luck...Randy

Ken,

We should be able to do a bit better than $190.

We've got lots of take-offs.

Give Peter a call. 860-224-0253

Thanks Randy and Bob, it looks fairly straight-forward...
I need some Christmas goodies to give my car anyway, I'll give ERA a call!

Ken,

I've done mine and it is doable if you're the mechanically inclined type. A couple of pointers though:

1. There's a stainless steel or brass spacer on the stub axle. Don't assume that the one you have now will work on your new hub assembly. They come in thickness ranging from .110 to .138 inches thick. You must measure and get the right one.

2. ERA has some pointers on how to set the bearing up right. Check out this info: http://erareplicas.com/427man/jagrear/rhub_axle.htm

3. You don't need to have a press or pay someone to press the bearing on or off.

4. To get the wheel hub flange off the hub, just rest the angled side of the hub on a step and use a hammer to tap the hub flange off. Works like a charm.

5. If you're replacing the outer wheel bearing, you will need to rent a bearing puller to pull the outer wheel bearing off the hub flange. I think I payed about $5 to rent one.

6. You don't need to press the new bearing on either. Just put the hub flange in the freezer for a couple of hours and the new bearing in your oven set at about 150F for a few minutes. The bearing should slide right on or need just a slight tapping to get it on.
