It happens. One year after spending a bunch of time fiddling with =
Peyote=92s suspension, adding TR4 bits, adjustable camber, and =
eliminating bump steer I went on the track for a test and tune day, and =
the car was horrible. Darting everywhere. Took it back to the shop and =
discovered I had everything reversed side-to-side, and so had the TR4 =
caster backwards. What happened is that after I got everything the way I =
wanted it, I took it all apart and painted the parts, then put them on =
bassackwards. Sheesh.=20

Unbelievable, but the left lower trunnion is mounted on the right side =
of the car and vice versa. I have worked on the front suspension during =
5 evenings till 01.00 am and still didn't see it, although these =
trunnions are marked RH and LH. I noticed it this morning when starting =
to fit adjustable upper inner fulcrum pins. When correctly fitting the =
lower outer trunnion bolt, only the part of the upright that is screwed =
in the trunnion is allowing a little movement , the upper ball joint =
could not be forced between the upper (original)wishbones. This is the =
case on both sides of the car and the upper ball joint is 1cm more to =
the front than the lower trunnion when the car is level(=3D a little =
negative caster). I'll report on this forum when I've swapped the =
trunnions and uprights next week.

I use them on my TR3 to get negative camber without modifying/shortening =
the upper arms.  These adjustable pins can be flipped depending on the =
ride height.  They also come with spacers that fit between the ball =
joint and the A-arms for further caster adjustment.

understand what you mean, I don't believe this is correct : the trunnion =
bolt is clamping the distance pieces (short pieces of steel tube that =
slide over the bolt and rotate in the outer wishbone bushings) onto the =
trunnion and hence the bolt, trunnion and distance pieces should rotate =
together and only the wishbones can rotate in respect to the bolt (and =
trunnion and distance pieces). I have assembled the suspension in this =
way, eliminating thus the play of the trunnion on the bolt and this is =
the reason I had to drill new holes , more to the rear, in order to get =
the upperr end of the uprights between the outer ends of the upper =
wishbones. All parts and also the chassis seem to be all right. Maybe I =
get it wrong anyway with the assembling of the suspension parts

just the brass piece that fits in between the lower wishbone arms and a =
bolt slides through it, instead of the fulcrum pin (pressed into the =
trunion), as you would have had on your TR-3.  The lower trunion should =

at the Zandvoort circuit (The Netherlands). It's a great car and it will =
get better. Of my TR3, I only kept the engine and overdrive dogbox  =
Overhauling the front suspension, I found that the lower trunnion was =
moving on the bolt instead of the bushed lower wishbones : the distance =
pieces in the wishbones where shorter than original, so the trunnion was =
not clamped by these distance pieces when fastening the bolt. Correcting =
this, the upright has less play now, only a little in the trunnion, and =
this upright with balljoint can't be forced anymore between the outer =
ends of the upper wihbones, the balljoint is 1/2" too far to the rear. =
Turning the upper wishbones to the rear (by moving the fulcrum pin) =
isn't a good option, because binding will occur. I've drilled new holes =
for the brackets for the inner ends of the lower wishbones : the =
suspension is moving without any binding now but I don't know if I will =
leave it like that. I wonder if something is wrong with the uprights? =
(less than 3=B0 caster?) If I measure the caster, I find 2.2=B0 on both =
sides, but probably that isn't proving anything. The chassis is as new, =
no damage. Any idea's someone?

by moving the steering rack is a J : the wheels are toeing in when =
lowered more than 3 cm below ride height (minimal to 5cm, then more and =
more toe in). Bending the steering arms to the outside, almost touching =
the brake disks now, has straightened the J a little.  Is it possible to =
eliminate the bump steer completely, or have we(TR4A-TR6) to accept some =
bump steer in the least important part of the suspension travel?

June&nbsp;2014 I bought Bob Kramer's TR4A racecar after I crashed my TR3 =
at the=20
Zandvoort circuit (The Netherlands). It's a great car and it will get=20
better.&nbsp;Of my TR3,&nbsp;I&nbsp;only kept the engine and overdrive=20=

dogbox&nbsp; Overhauling the front suspension, I found that the lower =
trunnion=20
was moving on the bolt instead of the bushed lower wishbones : the =
distance=20
pieces&nbsp;in the wishbones where shorter than original, so the =
trunnion was=20
not clamped by these distance pieces&nbsp;when fastening the bolt. =
Correcting=20
this, the upright has less play now, only a little in the =
trunnion,&nbsp;and=20
this upright with balljoint can't be forced anymore between the outer =
ends of=20
the upper wihbones, the balljoint is 1/2" too far to the =
rear.&nbsp;Turning the=20
upper wishbones to the rear (by moving the fulcrum pin)&nbsp;isn't a =
good=20
option, because binding will occur. I've drilled new holes for the =
brackets for=20
the inner ends of the lower wishbones : the suspension is moving without =
any=20
binding now but I don't know&nbsp;if I will leave it like that.&nbsp;I =
wonder if=20
something is wrong with the uprights? (less than&nbsp;3=B0 caster?) If I =
measure=20
the caster, I find 2.2=B0 on both sides, but probably&nbsp;that isn't =

anything. The chassis is as new, no damage. Any idea's=20
