Hi\nI have a 96 2.0 Vectra which makes a very loud clunking noise coming from\nthe front and the car lurches as if misfiring. Sometimes it causes the car\nto drive off the line it was going in and I can feel "something" similar to\na pull through the steering wheel but it is not violent. It's not constant\nand more frequent in low gears. Changing into 2nd and pulling off while\nturning right seem the most popular times. It lasts a few seconds and then\nI can drive normally. Then I come to another junction and have to slow up\nand chances are it does it again. Due to rush hour traffic I have not got\nmuch higher than 3rd gear since it started but the one long section I drove\nin 4th was problem free.\n\nAny ideas? Driveshaft / joint related?
