Steering wheel vibration Options

[tsvo]

Hello, I have a vibration that I can feel through the steering wheel, especially as speeds increase. I have had the alignment done, replaced the tires and replaced the struts.

Any suggestions on what to look for next?

I have been fighting this issue for a couple years now. Tried everything listed above, road balanced 3 times before we solved 80% of the problem, even had the rims sent to FUCHS restoration. In fact my car is back at PMS to address this issue alone with other steering related issues. Maybe I need to follow Mikes advise and take a road trip to Roger Krause Racing in Castro Valley.

Short term flat spotting is a very real issue on modern tires post Firestone/Ford/TREAD Act fiasco. Design changes were driven into tire construction that compond the short term flatspotting issue. Occurs across all tire brands. Some constructions worse than others but it is there in all to some degree. Most temporary flat spotting will drive out in just a couple miles but there are constructions out there that require tires to get pretty warm and even then it still can take 5-10 miles for it to really settle down.

If you are really having road balance issues, my preferred solution is drive them enought to get them very warm. Take all tires off the car, leave them on floor in horizontal orientation overnight (Don't stack all 4 vertically either), then do road force in the morning.

Also worth noting some constructions have long term flatspotting that if left long enough (say about 6 weeks) it will never drive out. It won't be terrrible but it will be present and will not go away regardless of what you do. Is even worse if parked when hot, and then left for that extended duration.

If you can't seem to get that last 20% try an on-car wheel balance. Getting hard to find shops that can or will do it but on-car balance accounts for all rotating imbalances including rotors, and/or rear axles & outboard CV's.
