[Healeys] Suspension bushings - tangent

[Bob Spidell]

FWIW, I've had PU tie rod bushings for probably 50K miles or so with no 
issues (I have a Texas Cooler fan, with only about a quarter inch 
clearance with the radiator tank, so it's critical).  Same with front 
suspension--including sway bar--but the damn things squeak.

Not to brag--OK, I'm bragging--but I'll bet I drive my BJ8 harder than 
most; about 5K miles/year over all kinds of roads, which makes it a 
pretty good test bed.  Worst road ever: drove through Cholame, CA to 
check out the James Dean memorial and took the Parkfield-Coalinga Road; 
north of Parkfield it's a one-lane dirt road.  It's hard as concrete and 
must have had a lousy grading job--think the blade must have been 
'skipping'--that made it essentially a large washboard.  Ten miles or so 
of constant, rhythmic pounding that could shake the fillings out of your 
teeth, but the suspension held together.
