NC280z Posted November 15, 2020 Report Share Posted November 15, 2020 Good evening all! I've finally located the cause of a mild, persistent wheel shake. It would appear that the driver's side front wheel hub has a slight ridge near the rim between two of the studs, which is preventing the wheel from mounting flush. The ridge isn't significant and should be easy enough to flatten, but I'm looking for some guidance before I take a drift to it. What's the best way to flatten out the ridge? OEM hubs are NLA, so I'd be looking at T3 replacements if I can't fix the stocker. Quote Link to comment
datzenmike Posted November 15, 2020 Report Share Posted November 15, 2020 Rust? or damage? Maybe something was crushed between rim and hub? It should just flake off. It would have to be hit pretty hard while the rim was off. Touch it up with an angle grinder. Wheel shake is more likely damaged rim or tire or out of balance. Quote Link to comment
NC280z Posted November 15, 2020 Author Report Share Posted November 15, 2020 I thought it might be a wheel/tire, but I've swapped wheels and only the driver's side has the shake. I've got the car on stands and when you spin the wheel it's pretty visible that the wheel isn't evenly mounted to the hub on the driver's side, due to the ridge. I'll go snag a photo and post it shortly. 1 Quote Link to comment
thisismatt Posted November 15, 2020 Report Share Posted November 15, 2020 Grinder, flap disc, file? Quote Link to comment
NC280z Posted November 16, 2020 Author Report Share Posted November 16, 2020 Looks like filing it by hand was the solution, don't know why I didn't think of it before. I'm honestly just surprised that the hub had been damaged, I have no clue what could've caused it. Quote Link to comment
datzenmike Posted November 16, 2020 Report Share Posted November 16, 2020 That obviously has been hit hard by something displacing the metal. Maybe the entire strut with spring might have been dropped on concrete. 1 Quote Link to comment
thisismatt Posted November 16, 2020 Report Share Posted November 16, 2020 Flap disc is what I would use, or have a machinist chuck it on the lathe and flatten the whole thing. Shouldn't cost too much. Quote Link to comment
iceman510 Posted November 16, 2020 Report Share Posted November 16, 2020 I had a similar ding on either my 280ZX or 300ZX hubs, can't remember which. I hand-filed it too, but if you still have issues, I would do as Matt suggested and have it very lightly touched up on a lathe to make sure the surface is true. I think mine happened from being dropped when not attached to the vehicle, or maybe someone hitting it with a hammer when removing them from the car (junkyard did the removal). Quote Link to comment
datzenmike Posted November 16, 2020 Report Share Posted November 16, 2020 Hand file it down. More control that a grinder. Can't see the rim and tire being off enough for any wobbling. Quote Link to comment
MikeRL411 Posted November 16, 2020 Report Share Posted November 16, 2020 Slipped off the jack while changing tire ? It doesn't take much of a drop to upset metal on a disc brake. Quote Link to comment
