Have replaced kingpin's and new bushings. Had bushings honed, everything tight. No slack anywhere, still have a little shimmy at 60 mpr and goes away above 65 mph. Steering feels good not too tight and can feel no slack in gearbox or linkage. Don't know where to look next. Al

Make sure the tires & wheels are true side to side, balanced, and of course round.

JSeery · 10-10-2018, 10:59 AM

Sounds like a tire/wheel issue.

aussie merc · 10-10-2018, 02:10 PM

find some one that can on car balance as this will balance the whole rotating mass not just the wheel and tyre [ a tip if you can use a paint pen and mark the end of one wheel stud generaly closest to the valve this will allow you to refit the wheel in the same place if you need to remove it at any time ] the only down side is you need to rebalance if you rotate your tyres

I've experienced that by having the wheel bearings adjusted too loose.

Yep , that will do it !

grumppyoldman · 10-11-2018, 10:01 AM

I have the bearings pretty tight now, don't know how much more they will take. Brake drums balanced , wheels and tires re-balanced, new tires, steering stabelizer, rim run-out, tire run-out wheel wobble, nothing seems to correct problem. Still looking. Al

Did you replace the rubber ball on the wishbone? That can cause a problem if the rubber is worn out.

J Franklin · 10-11-2018, 10:59 AM

Has the car had a front end alignment?

grumppyoldman · 10-12-2018, 12:02 PM

Checked the wishbone for wear, none there. Alignment done, still looking. Al

J Franklin · 10-12-2018, 12:42 PM

Are the brake drums round? maybe on side is hitting a shoe every revolution. We are running out of possible causes!

grumppyoldman · 10-12-2018, 02:30 PM

Going to have the rear tires road load balanced, been working on front end all this time and realized it could be something in the rear tires. One looks to be out of round, don't know what the amount should be to be true enough. Al

grumppyoldman · 10-12-2018, 05:14 PM

Just had the tires road load balanced, one read 10 the other one read 51, don't really know what those no. mean. The guy that did the balancing said the 51 no. showed the tire was bad and I could see what looked like a lump on the tread when rolled by hand. Trying to get it replaced, wish me luck. Al

What brand/size tires are you running?.

From another post in another thread, he's running "Corky Coker" Specials. Following the progress on a replacement of the 'bad' one will be interesting. Good luck! DD

Coker Tire Co. rep. said I would have to go through Discount Tire to get the tire replaced. It being a weekend it will be next week before I find out what they will do. The tires are new and only have a few miles on them, mostly only trip's to Discount for balancing. They let me watch yesterday while the balancing was done (Road Force) I could see one tire had a lot of run out, the other was not bad. Al

grumppyoldman · 10-15-2018, 02:44 PM

Have new replacement tire on it's way, will have it road load balanced before installing on car. Am going to check balance on rear brake drums, by installing them reversed on front drums, which have been balanced already. Don't have or can't find another way to check them. Al

This REAR DRUM thing, besides being almost impossible to realistically and physically pull-off, is probably going a bit too far, although I do realize your frustration. If you can't balance a drum as an eventual ASSEMBLY in a "to be used" condition, you're probably whizzin' UP a tree. You done good gettin' another tire on the way that easily. Again, good luck! DD

grumppyoldman · 10-16-2018, 09:35 AM

I've replaced the one piece hub and drum with the hub and drum that can be separated. hope to be able to take the drum's off by them selfs, turn them around backwards, mount on front drums and see if I can find a heavy spot. May so maybe no. Al

grumppyoldman · 10-18-2018, 04:26 PM

New tire mounted on car drove, it's better but still a little shimmy at 65-70 guess I'll swap positions and see if that helps. Al
