R34 Gtt Pulling To Left

[mystery_kid]

my car has had a pull to the left for a while now, it has had a few alignments over this time and it hasn't ever seem to fix it

it has had new tyres put on in january this year, there are new (less than a year old) rubber bushed adjustable castor arms and bearing jointed camber arms up top and the tie rod ends were replaced with ball jointed items about 18 months ago the day before i bought the car as part of the road worthy

i can't quite confirm but sometimes i think there is a very fine vibration coming from that side, which had me thinking today possibly wheel bearing

anyway i jacked each side up before and there isn't any movement when i grab the wheel on top and try and move it but when i grab it either side and move it there is a small bit of movement, the right side wasn't as bad

so i'm thinking it's either to do with the ball joints or maybe the steering rack has some movement?

wheel alignment specs

camber: -2.5º both sides

toe: +0.5mm each side

castor: about 6º i think

any input would be great thx

When you say side to side I assume your grabbing the tyre on the left and right and moving it? Not top and bottom?

If that's the case the rack end is probably worn and the alignment specs may look good on the machine but are out due to movement while driving

Either way a competent wheel aligner should have checked these things for you?

Checked brake pistons? Pads wearing evenly? Have you got adjustable castor arms? Road camber will tend to make you drift to the left a lttle - you can run 1/4 to 1/2 deg more camber on the left to compensate.

(BTW check the rear brakes for dragging as well)

primative, but works..

Measure the distance from LHS front axle to rear, then RHS front axle to rear. LHS and RHS should be the same, there's even a chance the stock subframe bushes are farkkkked and the subframe is sitting a tad off.

yeah johnilicte the last wheel alignment i had done there is a measurement on the sheet that measures exactly that and there isn't a major difference

the movement is left to right so it's probably the rack end, sort of surprising as they aren't that old but at the same time not that surprised as the old front tyres on it managed to destroy a ball joint on a castor arm in about a month due to the vibration i was getting (old worn federal rsr's)
