Trailing Arms Question
« on: August 07, 2009, 13:31:27 »
Does any one know the thread type for the rear lower trailing arms for a Ranger Rover Classic. I thinks its M20 X 1.5?

Just measured mine and it seems to be M20. Standard M20 pitch is 2.5. My aftermarket arms are this. Metric fine would be 1.5 like you suggest.

Most likely 'it depends' - imperial up to some cut off date, metric thereafter?  Around 1989 at a guess.

Well mines 1987, but the trailing arms have been changed a few times, what would the original thread be for that year?

you want the trailing arms with the larger thread. as the ones with the thin thread have a tendency to either strip the thread or bend easily when you are of roading.

The threads on my trailing arms (from 1986/7 range rovers) are M20x2.5 course thread.

Basically a Carb'ed RRC would be imperial and the thread is much tinnner but it's also a finer thread so as said is gets damaged, especially once it's rusted too.

Later (EFI onwards) should be M20 the same as the front radius arms which changed at the same time (thicker axle bushes etc).

The axle to trailing lnk bush remained the same AFAIK, along with the A frame and Panhard rod.
