Hi All,

I'm in the middle of a chassis refurb and am getting ready to put wheel bearings to front hub and assemble those. I'd bought about a year ago 4 x Grand Cherokee wheel bearings '93-98 which have a model number of KLP-CH-011 on the box and stamped on them.

The issue is that the inference fit with the hub is too tight, so although it fits in the hole, it sits proud and even tapping it with a rubber mallet doesn't really make it sit snug - and so it would look as thought they're not the right bearings - I've put a picture below;



I've tried tightening down the cap bolts but it goes so far and then basically sits proud by about 5-6mm.

I had followed another thread which seemed to describe this issue, but the bearing I'd ordered for that one is a Grand Cherokee '99-04 and the stud pattern is way bigger than the '93-98 ones I have already.

So I'm just not sure whether I have the wrong wheel bearings completely or what to try next, don't want to order any more until I'm sure otherwise I'll be able to open my own wholesalers soon smile

The ones you have fit the rear but not the front?

It is down to the shoulder shape on the back of the bearing. There are 2 which are similar but one type fits front and rear, the other rear only.

Thanks Johno, you know I haven't tried the rears I just tried them on both of the front hubs. Is there a way of identifying which ones the fronts should be?

I'll try them on the rears later and report back.

Have you painted the hub upright? It’s not the thickness of the paint stopping it sitting in?

The hubs have been painted, however, I've peeled back the paint and it was very bright underneath have spoken to the company who painted them and it looks as though they may have been galvanised as well :nuts; so I suspect that the whole thing is just too tight.

After 20 minutes or so with the dremel it seems better now seem to fit at the top and one side but not seat all of the way in - will speak with a local engineering company and see if we can machine it somehow so that it will fit, otherwise will have to purchase two new hubs!

The hubs are aluminium, they won't be galv'd.

Success at last!

The simple answer here is just buy the right parts in the first place smile

I think I was trying to save money, have bought them from TVR parts and they fit perfectly - looking at them side by side, the one one on the left is the TVR Parts one and then one on the right is the ebay one you can see that the 'shoulder' is machined ever slightly too big and so it doesn't fit in. I've put a picture below so you can see the difference;
