shake at high speed

[Gccch]

I've been noticing a shake in the steering wheel which has stayed with me even after the front wheels were rotated, aligned and balanced. Rear wheels have not been touched. It starts off as an on/off shake. Steering wheel will vibrate for about one second, then not for about one second, and continues like this from about 75 mph and up. I think (not sure) it becomes a constant shake above 85.

Where to start? Rear wheel balance? Drive shaft? Car has almost 22k on it and still running original rubber.

Your running 14 year old rubber at high speed? Good luck with that. Rubber is probably hard, might want to think about new rubber.

Tires are junk, slipped belt etc. you shouldn't be running tires older than 5 years of age.

What they said^ have you had the driveshaft taken off at all? Check to make sure everything is tight.

What they said. Time for a new set of sneakers.

You need new tires.

An out of balance driveshaft is usually felt in the seat, not the steering wheel.

It's unanimous. OK, I guess I better burn off the remaining tread.

Ahem... You might need to make a decision first ;)

Right you are. I'm going through it all. The struggle is real.

If you haven't had the tires replaced on these wheels yet -- Be sure to use a more high end tire shop, let them know the wheels are NOT EASILY REPLACEABLE ($400 each if you can find them) and that they need the "white glove" treatment.

You also need to ask for a "road force balance" for the tires, chrome valve stems, and wheel matching low profile silver weights.

Suggest NITTO Motivo's or 555's depending on where you live.

this also was the only thing that finally fixed my issue road force balance only issue was I wanted the weights behind the spokes and the shop didn't know how to do it, so I asked if I could show them they said yes, so I spent about an hour teaching the shop techs how to use the balancer and some of its lesser know features all told in the end I got my tires balanced for free and the shop gained some new knowledge. Oh and I got offered a job, ha ha lol
