Just got back my car today from being in the shop for quite a while getting rewired and straightened. It drove decent, aside from a few minor things the shop didnt do, that I asked them to do. Tonight, while I was driving it, it started seriously acting up. When I would turn the wheel almost all the way, the horn would intermittently chirp, but that was its own issue. The serious problem was this: earlier in the day, when I would brake moderately hard (just had 4-wheel disk brakes installed) there was a sort of knocking sound that felt like it was either coming from the front left part of the suspension or from the transmission. It was hard to tell... Later in the night, I was driving a few people around, enough to weight the car down a bit (the car already rides fairly low in the back...I'm getting new shocks/springs) and when I'd be braking there was a serious rubbing sound, that evolved into a loud clanking. It wasn't too bad until about 15 minutes later, when the clanking was heard no matter if I was accelerating, cruising, or even braking. At that point, I was right near my home, so I just parked it. What is going on? It did NOT sound good. Some people have told me it might have to do with suspension linkage, but this seemed like more...almost like the transmission was grinding. For the record, it is a '67 with a mild 350ci, lunati cam/lifters, demon 750cfm, headers, original 2.73? rearend, new bushings, 4-wheel disk brakes...all I can think of now. Thank you very much to anyone who can help me.

Need details on what was installed on the car and what work was performed.
If this didn't start until the parts where added it's a good bet that's the issue.
Are the calipers loose. etc, etc . It could be anything. Get it back to the shop and make them test drive it.

John,
One more bit of advice .... I obviously cannot hear the noise, but if its as bad as you say I would not drive the car another foot. If you do not have the skills to determine what is wrong, then have it towed, on a rollback, to the shop that did the work so they can look at it. Its not worth the price of a tow bill to take a chance that a wheel might come off etc while driving it to the shop.

Wheels loose? If new discs were installed, there's the possibility that if the disc is held on the hub with the studs, after they're pressed in, that they didn't seat fully. This will allow the disc to rattle around between the hub and wheel. This will also mean your wheel will be loose. Easy to do, even on stock applications, if you're not expecting it.

There was literally a knocking sound that was at complete random thanks to my front bearings being so worn out they were miles from falling apart, thank god we replaced them when we did.
