Wobble in steering while driving above 50mph...

Hey guys... so, as I stated above, if I go over 50 in my 1991 Caprice Classic, I feel a wobble in my steering wheel, as well as smelling a slight burning smell. This wobble is accompanied by a pulling (hard) to the left. This information led me to suspect my front left wheel. When I got to my destination, I got out and checked out the wheel. When I went to remove the center cap, I could feel heat radiating from the rim, and after removing the cap, felt the lug nuts and they were HOT. Any ideas on what is wrong? Brake issue? Alignment or wheel balance? It's only the left front wheel... the other three were fine/normal after a half-hour drive. Thanks in advance!

-Chris


So what if I drive my grandpa's car?

First guess wheel bearing(s). Improper tightening, or, insufficient/improperly maintenanced lubrication. Unfortunately frequently overlooked for service in a timely schedule. Best to replace bearings and races as opposed to chancing just greasing the existing ones.

Could also be dragging/binding or generally fubared brakes, - caliper and/or rotor.

I would suspect the brake caliper. It could as well be the bearings, but you should be able to take the dust cap off, and see if there is any metal shavings in it. You could also jack the car up, and shake the wheel. If it wobbles, it is probably the bearings.

Chris, insert meme of me flinching here. Anything other than the most trusted shop will have a field day with your generic symptoms. Just as with an intelligent attorney you should never ask a question without already knowing the answer.

Even if you don't have anything more than a bumper jack and piece of 4X4, you owe it to your blood pressure, heartburn and pocket book to at least pop the wheel for prelims that point to a specific direction. It keeps expensive creative thinking and fiction to a minimum for the shop when the owner gets to (intelligently) participate in decision-making.

Cliffs: You probably WON'T need a new spindle. Or alignment. Or A-arm. Or master cylinder. Or tune-up. lol

Lol yeah... the above are definitely not the issue.

I did take the wheel off last night (forgot to take pictures), and from what I could see there wasn't anything obviously wrong. The dust cap was hot, the lug nuts were hot, and even the rim itself was warmer than the other three (I compared temperatures with back of my hand), and the wobble/shaking was not constant. There was, however, a little bit of a blackish-grey substance that looked like it had dripped onto the outside of the rim that was not on any other... not sure what it is...

As for a trusted shop, my ideal one would be back home where my family has taken cars for years (small town, trusted guy) but since I'm at school, I have a shop here that is greatly trusted by the local public and has done well by me so far... they will probably get to look at it before Spring Break


So what if I drive my grandpa's car?

In the absence of results from any more intel it could anything - as convoluted as the combination of bad alignment and a missing wheel weight and/or bent rim (shimmy), plus real low low pressure (heat) with a rotted A-arm bushing (pull). You tested both shocks and endlinks are good?

As it is you're writing someone a blank check.

Well, after driving a bit more, (with the windows down, as it has warmed up quite a bit) I have discovered there is also a randomly occurring, intermittent squeak coming from that same wheel while driving a slower speeds... not sure if that helps at all...
