Re: IML: Springs n things

It could be that your car needs to have the front coil springs 
replaced. HD should make it a little higher in the back, but I would 
look at the front springs before modifying the rears.

Also, if you rear end is sitting too high, you may have to adjust the 
drive shaft angle. Does this car vibrate on acceleration at around 30 
to 40 mph? If so, that is why. There usually are shims under the 
mounting for the drive shaft center bearing, and also at the rear axle 
support struts. These need to be added or subtracted in order to obtain 
the correct angle. The procedure is outlined in the FSM.

You can't change the hieght of the rear end without throwing this 
adjustment way off. If the car doesn't vibrate, it is probably fine, 
but it might vibrate with people in the back seat. Over the years, it 
is difficult to say what changes have been made. Even so, the drive 
shaft angle can be checked to determine if it is within specifications, 
and should be checked again if more work is done to change the hieght 
of the car.

Years ago I did the rear springs on my '56 and ordered HD. For some 
reason, the rear end has rode high ever since. They're installed 
correctly, but I have to keep a load in the trunk to keep it level. I'm 
wondering if I remove a leaf if that would help. Thoughts?
