: Assuming all else is tight, remaining possible contributors are : Loose wheel bearings : Loose ball-cup assembly at the rear of the front radius rod (wishbone) : loose tie rod & drag link ends or weak springs : Excessively worn steering sector shaft bushings : As far as the toe-in, most people don't know the correct measuring points. The toe-in is measured between the fattest point of the sidewalls, 6 inches above the ground, fore and aft of the axel, and should be checked only after driving the car forward. The measurement was changed in late 1928 from 3/16" to 1/16" (+/-1/32") to reduce tire wear. A toe-in above 1/16" will slightly increase stability but will increase tire wear. : The 1928 Leather back (60-A) is a nice car and definately less common than tudors & coupes. How early is it? : : : Trying to find information on my car. I'm told it is a rather : : rare body style. Can anybody verify this? The car is in great : : shape but I have a shimmy problem around 20mph. When car was : : purchased, it had not been driven for 10 yrs. Problem started : : as a high speed (30-40mph) shimmy. Rebuilt kingpins and checked tow in. Problem went away briefly. Checked steering : : box and it needed tightened. Corrected problem again but only : : briefly. Changed wheels due to left front rim bent. Thought : : that that would solve it, but again only briefly. Rechecked : : tow in with someone more knowledgeable. Adjustments made and this corrected it again but now shimmy at low speeds. If you : : speed up past 20mph shimmy will quit and run just fine. HELP!! |
