rear end alignment

[jsfbond]

I took apart the rear suspension, to see what adjustments are possible.

looking to move the housing 1/4 inch or so towards the driver side (that would be the left here in the states)for prop shaft clearance.

The rear housing fits like a glove into the frame.

no lateral options that I can think of.

should the drive shaft go between the frame and not on top of it?
seems the clearance would be there if it was between the frame rails, I know its not a TR6 but mine goes between the frame

In your last picture are the upper bushings being installed as they sit on the frame or or are they flipped over so the protrusion fits into the carrier not the frame?

I don't want to brag..but on a GT6 the shaft is too big to fit between the rails......The transmission is dead center, and can not be offset enough to make a difference back there.

The bushings were correct on invert/orientation in the mounting bracket.the inside of the bushings show a n offset wear, like the housing was tweeked to one side and then tightened down.I do not believe it would hold being rubber on both sides of the mtg. bracket.

I would start by getting new bushings and seeing if that results in the alignment correcting itself. The front bushings look quite distorted.

If it does not, there are not really any adjustments there.

Has this car (frame) been in any accidents? If not, have the brackets been re-welded? If the frame is distorted or the brackets were not welded in the correct location that would cause the rear to be out of line. Lets hope that it is just a problem of distorted bushings.

No accidents with this car, as I am the second owner. The only thing my crew here at the parts store could suggest is that the old bushings are hanging up/ not going/seating into the bracket, and therefore holding the front of the pumpkin down, and the shaft hits the frame. Still not talking a lot of clearance for this shaft.

 

[70herald]

try a new set of bushings. Remember that the back end of the car is held up by those bushings.

Here's a couple of shots of the differential. You can see the clearance around the drive shaft and the measurement at the bushings. Note that the frame rail is bent down where it is closest to the drive shaft. This is on a 75 Spit, hope it helps.

Nice pics, thanx. I like the looks of the frame rails bent down for clearance.

Did you find the cause of your clearance issue?

I did the same thing the "Technicians" who built the car must have done, by the looks of the wear pattern on the mounting bushing...I left the cross bracket loose, installed the prop shaft, and forced the rear housings nose over just enough to allow the shaft to turn free, and cranked the mtg. bushing tight. Then I put all of the other rear suspension and shafts back on.So far so good when I wheel it around.
