[TR] Light weight rear TR shock oil ?

[Carl Sereda]

 Hi Allen, 
You may remember some folks put teflon sheets in between each of the rear leaf spring's leaf layers.. talk about a job!.. 
I'd be hesitant using lighter weight shock oil although Wide World seems to make it sound Ok - bottoming out the live axle would be hard on the old back - am interested in what World Wide has to say about it currently.

I have a 62/63 TR4 (straight axle) which by definition equals a ?very firm ride?. I am wondering about replacing the damper oil with a lighter weight. Referring to Barney Gaylord?s page https://mgaguru.com/mgtech/suspensn/fs110.htm  the standard weight oil is about 20W or ISO 68 (Peter Caldwell World Wide Imports). Hydraulic jack oil ISO 32 is 10W and fully compatible. I will call World Wide tomorrow for clarification. Has anyone tried this?

I?ll also try to grease the leaf springs as that was last done when I restored the car 25 years ago. That?s a bit of a job and can open a can or worms since spreading the clamps around the leaves can sometimes break.
