So this weekend my uncle and me replaced both left and right inner and outer wheel bearings on my 80 coupe, after being done took it for a spin and I advised my uncle that I still hear a noise....fast forward to today. So Im driving and I hear like a click clack sound, get to work, remove hubcap and dust cap was loose, raised up wheel and THE ENTIRE ASSEMBLY MOVES WHEN HELD LEFT AND RIGHT AND TOP TO BOTTOM. I called him and he said that he tighten it and placed cotter pin. He says the only thing that he could think of that would loosen is the cotter pin. I replaced both with new ones.. he mentioned also that I should have left the old ones (cotter pins)
Is this true, I have never heard this before and now I don't want to drive car at all...what can I do...
PLEASE ADVISE..

Now it's a long way from here to your locale but this is how I see it....

you MAY not have seated the bearing properly when you fitted it and "tightened" the nut....

after a little driving the race / bearing has settled into place leaving a ton of slack (even though the nut may be fixed from undoing with the split pin)...

pull the pin, tighten the nut till the wheel has no slack (yet still turns freely) and replace the pin...

a quick spin round the block should confirm you have now got a correctly adjusted wheel bearing.

in future if you are not 100% happy with repairs you make check it out before you drive to work....

OK that's my two bobs worth...hope it helps.

The bolt shouldnt have came loose if the cotter pin was in, maybe it slipped out. How was the condition of the race inside the rotor? You should always replace cotter pins when needed, I buy mine in packs of like 10.

It looked brownish to me and the cotter pins were replaced; both sides. Do I just simply remove, tighten and reinstall pin and go from there?

If it were me, I would take the rotor off, completely clean the bearings and races, inspect, repack the bearings, and put everything back together. That's just me.

Hate to say it, but it sounds like you are in over your head. Get that car to a proper shop pronto!! You could have a ball joint about to go, bearings mis-adjusted, or any number of things worn or mal-adjusted. Most of this can kill you, ALL of it can cause a severe and sudden loss of control.

Next, take a community college course in auto mechanics.

Don't panic! Just take out the cotter pin, tighten it up like allbymangled said and it will be fine.

Or kill someone else if it falls apart while you're driving on a highway. If you're not sure of it get it checked out somewhere just to be safe.
