Brand New to forum. I have a 300d 1985 and when I am driving it to work, after 10 minutes, it starts to shake. It will only shake for a minute or two and sometimes its shakes BAD and some times only a little. It also does this on my way home from work. I've purchased new tires, changed the fuel filters, looked at the brakes and I didn't see anything wrong. Some times it doesn't do it at all. When it is shakes HARD, I will press on the brakes and they throb or go "UH UH UH"( sad attempt to produce a noise with words)
Is it my brakes? My calipers sticking? something wrong with my transmission? WHAT?
Thanks for any help at all.
