[Fot] Toe-in question on TR4

[malaboge at aol.com]

Brad-
If all the good recommendations that you've received so far leave you with
some percentage of the continuing problem...
Take a look at the rear leaf springs.  Check the front and rear bushes for
excessive wear/deterioration.  Also check the leaves for a broken leaf (look
closely near the axle mounts as this is where they brake if they're gonna).  A
loose/broken spring is tuff to notice but when starting into a turn, the
instantaneous roll oversteer from a moving rear axle due to the above will
really get your attention.
If its a 4A, check the rear control arm mounts or for a cracked frame for the
same reasons.

Oversteerin all over Nor Cal...
Nick

Subject: [Fot] Toe-in question on TR4


Amici,
My question is on my street TR4.  I've rebuilt the steering rack,
eplaced the tie rod ends, new Kumho 195/65R15 tires on new mini-lite
eplicas.  Stock front suspension components with the 3 degree castor
runnions.  The suspension is tight with no slop in the steering that I can
etect.  Toe-in has been set to 1/16" (I read somewhere that for radials this
ould be the appropriate setting).  Smaller diameter later TR6 steering wheel.
he problem is when coming into a turn and when you first start turning the
teering wheel the car acts like it wants to start turning and then it feels
ike you're plowing into the corner and it seems to not want to make the turn.
t takes two hands on the steering wheel to make the turn.  Also in straight
head driving it seems real twitchy.  In other words a slight movement of the
heel either direction and it seems to over react.
So, is this a toe-in
roblem?  If so do I need more toe-in or less toe-in?
Years ago I had a 73
R6 and I don't remember this kind of response from the steering.
Other than
his issue the car rides smooth as glass.
Any suggestions?
Thanks,
Brad
