my sincerest apologies. he actually showed me were the problem was, but like i said i don't know the proper terminology and i'm just using what i remember. he had the suspension off. it was the arm that had the housing for the studs, and he did say that the bearing could be replaced, but that just changing the whole spindle might be easier. right where the studs are, i moved it around myself and it did have play, and to my understanding it shouldn't. like i said, i think i'm just confusing you all.
First off, no apologies necessary. At one time all of us knew nothing about cars or car terminology.
Now with regard to the bold text in what I quoted of you above:
You're not confusing us at all. If anything, your mechanic has got you confused because you still keep thinking that the spindle can be replaced and the whole problem will be solved. Let me give you a break down of the parts that make up the hub assembly...
A wheel bearing is press fit into the hub. A big C-clip holds the bearing in place. A spindle containing wheel studs is then pressed into the wheel bearing while it's already in the hub. This means that to get the spindle out of the hub so you can replace it, it must be pressed out of the hub. Once you do this, the bearing which held the spindle into the hub separates as it is also comprised of several pieces. One of those pieces being the inner race, will stick to the spindle as it is pressed out. This is what destroys the bearing causing it to need replacing as well.
I think your mechanic is guilty of an "illegal use" of the word SPINDLE. People often refer to the whole hub assembly as the spindle. That is wrong because the spindle itself is just the portion that has the studs in it. I'm almost certain your mechanic is advising you to just replace the whole hub assembly. This makes things much easier for him but also makes them very expensive for you.
Let me explain: He probably doesn't have a hydraulic press and that's why he's suggesting you replace the whole hub assembly. Well, the thing with that is you should never have to replace a whole hub assembly unless you've gotten into an accident and it is bent. And if you do replace the whole assembly, you almost undoubtedly have to go with a junkyard piece because that part from the dealership would put you in the poor house. Well, here' the thing with that... you shouldn't replace an entire hub assembly with a used one and not replace the wheel bearing with a new one. For if you don't replace the bearing, who is to say this new old part is any better than the one you have in your car? And even if it is, how long before it gets to where yours is right now?
Your mechanic is making things difficult for you by trying to keep it simple for him. Get a second opinion. Go somewhere where they have the ability to install press fit bearings. btw- flat rate labor for a bearing is 1.5 hrs.
