[TR] Lower A Arms & Zerks

[CarlSereda at aol.com]

A,
Late TR suspension A-arms are different than early A-arms. The TR4/4A Factory 
Workshop manual gives 2 different diagrams/measurement instructions for 
straightening TR4 arms versus straightening TR4A arms. Therefore I would not 
install TR6 arms on a TR2.
'Greasing' spec changed to 'oiling' between TR4 and TR4A trunnion design. 
There was a big change in trunnion design for TR4As and beyond. (weaker design it 
turns out)
But the weak point with the earlier design (which I found on mine) is the 
trunnion 'cross shaft' wears through the soft brass bushings and into the iron 
arms themselves. Neil Revington prefers to install pairs of sintered (porous) 
bronze bushes at these outer ends (harder wearing and they don't require reaming 
as the brass ones do). The gap between the bush pairs allows grease entry. 
Neil still uses grease as originally spec'd up to TR4. You might want to find a 
restorable set of TR2(TR3?) A-arms and straighten them and/or get ends sleaved 
if needed, before rebushing them.. I had to buy all four TR4 A-arms for 
$100.00 at TROnly and beat them with fire and hammer back to factory specs (bushes 
were'nt worn through, so I could remove them and pop in new bronze bushes 
without a machine-shop visit for expensive sleaving)
Good luck,
Carl
