Made good progress in solving reverse judder (M46).
Removed driveshaft to replace suspected center U-joint. BUT: U-joints tested good. Smooth movement, no binding, no play, so I removed the plugs and greased them (temporarily installing 1/4" x 28 zerk fittings), and reinstalled driveshaft.
Rear of car appears to sag, springs look tired. Rear spring replacement planned for the future. Meantime I raised the position of the center bearing carrier 1/4" by inserting three 5/16" washers per side, between the chassis bracket and the brg carrier, bolt thru.
This lessened the reverse judder by approx. 50%. Might try shimming more (for 1/2" total) but first want to try replacing the soft panhard rod bushing, and trans mount.
