Steering wheel shake and vibration

[Scottjeffrey]

Hi All and Thanks in Advance. After 15 months of rehab I have my 74 on the road. New 13 inch tires and steel wheels. Replaced all of font end steering and suspension including steering coupler. New guibo and center support bearing. Rear brakes complete and rear shocks. While I felt it a bit at low speeds, I really felt it once on the highway. It doesn't feel like any tire imbalance I have ever experienced or front end issue, but what do I know. The alignment was done by a trusted shop. The car is tracking very well. You feel nothing in your seat. It's as if, to a novice like me, it is the steering column some where/somehow apart from the steering linkages or suspension. Made me wonder about current safety. I have not touched the steering box. Any help would be appreciated sincerely.

Best Holiday Wishes,

Scott

Rotate the tires front to back and see if that changes anything it could be a broken of shifted belt in one of the tires, then make sure the front wheel bearings are in adjustment. Did your front end rebuild include new ball joints?

Hi Marty. The ball joints are new. I will rotate the tires and check the new wheel bearings adjustment. Thank you very much!

+1 on rotate tires and check front wheel bearing play.  If they are new, bearings need to be reset after a short period, in my experience.

Hi Marty, Moved tires as recommended. I would say there was a significant improvement but still not right (I believe). Checked each front side by holding tire at '6 and 12'. No movement ones side, a little bit on the other side. I am thinking to remove cotter pins and adjust all over again but I won't be able to get to it till the weekend. Any thoughts? 

Warm Regards,

Scott

Have a look at the rubber disc in the steering column next to steering box. Perhaps re-balance the tires?

Thank you Hans!. I just replaced the steering coupler in the column. I may very well have the tires rebalanced.

It may take several attempts at balancing. Use a good shop.
