280z Steering Wheel Vibration

Your wheel bearngs are loose.  Even though there is a somewhat complex process for setting tapered wheel bearing preload, you can get really close just by tightening them by hand.  Pop that cap off and turn the nut until it's hand tight. 

Your aftermarket lugs are so long it wouldn't be a surprise if they were bottoming out in the nut. That rust and corrosion on the hub should not be there, where the nut is supposed to be clamping the wheel down.  That's a sign that the wheel is not seating on the hub.   

 

We can finally celebrate! My steering wheel shaking is gone!

I re-checked every single bolt in the front suspension (for the third time), removed the steering knuckles even and tightened the bolts for the bolt joints. Removed my wheels and removed all the rust on the hubs and backside of my wheels. However I think the fix was the front bearings! Even though I followed Nissans procedure for the wheel bearings I think they might be too loose for my suspension setup with hind joints and poly bushings. I tightened the nuts for the front bearings just a little more making sure the hub can still spin nicely obviously. All this and steering is solid! Crazy to think I went though two sets of bearings following Nissans procedure only for it to be the problem haha. To everyone with modified suspension and getting wheel shake, tighten the bearings! Thank you to everyone for helping! appreciate all of your for the help!

tighten the bearings! 

Keep an eye on the temperature of your front bearings, if you suspect problems take a ride and do all the braking with your e brake, then after half hour drive measure the temperature of the bearings.. just in case..

Will do, I think it'll be fine I barely tightened the bearings about a quarter turn and used really good bearing grease. Just to be safe however you wouldn't happen to know what the max temp the bearings should be at?

Hihi.. not in Fahrenheit!  Lets say if you touch the aluminum wheels (somewhere in the middle) and you have to pull back fast because it feels to hot to let them a few seconds on there, that's most times to hot..  Normally if you drive an half hour with lots of hard braking you get the same result, those wheels get very hot.. (That's normal) Take a look at the container/user manual of the grease you used! It should say something about temperatures..

It does remind me of a time i drove a sunny coupe to work very fast.. When i came at the firm and stopped and got out there was a black plume of smoke over both front wheelarches! 😁
