hello
awhile ago i replaced the front buckle bushings and the rear trailing arm bushings on my 66 230.
the car drove ok after replacing the bushings but i noticed a vibration around 70 mph that would come and go.
so, took the car to my favorite indy shop to get the car aligned.
1. Front.
we could not get the front caster perfect even by loosening the trans mount plate bolt, the 8 sub frame mount bolts (4 drivers and 4 passenger) as well as the buckle mounting bolt and the eccentric bolt. applying leverage etc to help but could not get if perfect.
We ended up at 4.3 deg drivers and 3.6 degrees passenger. I am not sure if there is anything else
I have never changed the upper spring rubber doughnut on the front, i am not sure if this affects caster or not
2. rear we were at -1.3 camber so we removed the rear springs and turned the metal spring plate to its highest position. we eneded up at -.2 or so.
the upper rubber doughut on the spring was changed about 13 years ago, i do not recall which thickness i used.
i believe i can get upper rubber with different thicknesses. i was thinking of finding out what i had installed and then going to a thicker rubber doughnut.
the car drove fine home, no issues.
The other unknown is i know my clunk bushing needs to be replaced. would that impact rear camber?
thoughts on where to go from here or should I leave well enough alone?
photo of the alignment tool after we had messed with the rear camber, need to drive the car to get things to settle down again.
prior to messing with the rear the caster was 4.2 (drivers) 3.4 (pass) and rear camber was -1.3.
thanks
matt
