  • Vibration

    I was driving my car home this evening and noticed a vibration and scraping sound on the right side only as well as some vibration in gear lever.... any ideas? is it possible that the bolt on the drive shaft are not tight enough or is it new car jitters? after spending so much time and effort putting the thing together I want to make sure everything works right.

    Can you give some more descriptions of when you hear the noise? Is it high/low pitched? Coming from the front or the rear of the car? only on turns? etc.

    If you jack the car up and rotate a wheel do you still hear the noise?

    One place to look: the transmission can be too far to one side or the other in the transmission tunnel. This causes the transmission to contact the chassis.

    In any case, yes, you should check the propshaft bolts if you have any doubts about them!

        I took a look at the transmission, it's about the width of a large paper clip (thickness wise) away from the cross members in the transmission tunnel.

        The rubbing sound was coming from the right rear area, I looked at the link that Magnus sent and the ebrake cable moves around a little on the chassis side, so I think that is where the grinding is coming from.... when I turned the rear wheels by hand the only noise I heard was the brake pads rubbing.

          Ahh. I've zip tied my hand brake cables to the chassis so never ran into that. A quick fix if that is what is happening.

            I think I found the scraping noise, the ebrake metal cable housing was pressing against the half shaft on the rightside near the differential.... I've zip tied it so hopefully that resolves the issue.

              Yep. That would definitely fit the profile of the sound.

              As you pull a sweeping left turn, the right suspension compresses and the half shaft will make contact with the e-brake cable.

              Good that it doesn't seem to be worse.
