Thanks for the info Joey and Punk. Its a front wheel. I had what i thought was a good garage look at the rover, it was there for 2 days, they did nothing, not even an estimate and i have been going there for years! They told me about the wheel bearing so me and a friend are going to tackle the pick up tube and look at the wheel bearings. Im a welder (Union Boilermaker) so i have had fun with 6010 (love the toxic smell of that and jet rod). when we see what we have when i get the wheel off, i will go from there. I just hope the engine knock isnt anything worse than we can handle. it doesnt knock till it warms up and you cant hear it when you are on the gas (or is a bearing contracting and wrapping when hot, i HOPE NOT).
