All,

I hate asking questions that I should be able to determine for myself but sometimes I just don't get it! For our front wheels, I have rebuilt both upper and lower A-arms (sandblasted, inspected, painted, new polyurethane bushings, they look really nice).

Bearings seemed fine on the coach, but put the hubs on my bench and drivers side has a "catch" in the bearing, turns ok except for a "catch" once in a while, feels like something is amiss so was planning on replacing.

So here is my question, I know that Timken Set23 is the recommended bearing (correct?).
How many do I need to order? 2 or 4? Cant really tell from pictures if the "set" has one or two bearings in it.

Also is there a bearing puller/installer tool loaner program in affect anywhere? If not what is the recommended tool?

Thanks All

Rich

Rich,

Answering questions is why most of us are here. (The others here and some of the same are here to ask.)

The "catch" maybe either foreign material in the bearing or that one of the races has come out of line. It does not take much, but this sure it the time to fix it. It either outer race comes out easily, come back here for advice. They should not be loose in the knuckle.

The Timken set 23 is two roller bearing assemblies and a spacer. (There is one set per side.) That spacer used to be set specific, but they processes have been improved so much that I am told it not longer is. But keep the parts in order as received just to be sure.

There were several bearing puller sets available on loan, but I never paid much attention to who and where because I expect I won't need them.
Arrange to borrow a tool set. I have seen this job done with standard tools and it is very difficult.

Also, while you have things apart, borrow the jig and drills to put a grease Zerk in the hub. That way future greasing can be done without removing the bearing. You will have to do some modification to the spacer mentioned above, and that can be difficult as Timken now hardens that piece.

Glad to see that you are staying up on the coach's maintenance. This will reward you with miles of pleasant touring.

Tonka6cuda6,
Matt is correct in that it comes in a set of two bearings and one spacer.
The spacer is required between the two bearings so as to set the correct
pre-load. That is why it is called a set.
