Hey Guys,

i could make a realy long story but i want to keep it as short as possible to keep it clear. ill try.

I drive a V40 D4 R-Design, MY15 with almost 200k km or 120k miles. last year i got a new electric Steering rack( @ 2000 euro), old one went bad, the new one failed after 4 months but after some investigation it traced back to a bad connector (rack connector to main loom).
After 2 weeks of getting the car fixed i drove over a parkingkerb in the parking lot at work after the late shift, with only my right front wheel at 10 Mph. drove at a straight line (or close to straight) over it but the kerb whas quite high, it whas a rounded kerb but about 20 cm or 7 to 8 inch high.

steeringwheel was a little bit off and the car felt really floaty and keeping straight on cambered road or with sidewinds whas really hard, car sometimes pulled left or right, depending on the road. Also 7/10 putholes i hit the car pulled on the steering wheel and steering wheel does return to full center (close to though).

so first thought: alignment, Went to a recognized shop to do a 4 wheel allignment (chasis 3 dynamic) with a Hunter system, it was indeed off but he got everything in the orange/green and assured me it should drive way better. after indeed it got better, straight line zero to no pull, but the car still needed correction al the time and still pulled on cambered road and on putholes the steering wheel moved.

bought set of 18 Inch Ixions 8J, since i wanted those already. this made the car way more stable but still needs a lot of correction on highway and hitting putholes or cambered roads the car can be really unpredictable and the car still pulls the steering wheel.

So after this i went to a Volvo Specialist and let them check the chassis and suspension, everything looks fine and all bushes etc are in good condition with no play. shocks are not leaking or anythin, also went for a drive with the mechanic and he said it didnt felt off...and that is just it, sometimes the steering feels stiff and fine and some trips it is just off, it feels like the wind plays a role here.

So the main thing that i find realy annoying, is that the car pulls the steering wheel on putholes and cambered roads. also not comming back to full center is annoying but i found electric steering racks do this more than hydrolic ones.
so since most of the possible problems are excluded, i came up with 2 possible problems but need some advice; could the brand new 2000 dollar steering rack be damaged this hard by just driving over a kerb at this speed? or should i look at new shocks since it it possible the front shock took the hit and is damaged inside without looking like it?

also i measured the side of the wheel to the body to see if the wheels are shifted back or forth(subframe?), the right front wheel which took the hit looks to be about 5mm to 1 cm further back than the left front(more towards rear wheel). also i measured that the front right seems to sit 0.5mm to 1 cm lower than left side. no broken springs.

greetings

morning! its worth looking carefully at the lower wishbone, any deformation may have been missed when tracking. and the rack, it could have been damaged (not likely but possible) I worked for a time in a bodyshop and it was standard practise to replace the rack on almost every VW Passat, even with no sign of impact

Well the wishbone i could check but seems okay, but would even the slightest disformormation fuck up the drive so bad? I'm guessing replacing shocks won't harm either but a new steering rack is way to much money, I got a lifetime ownership warranty but my dealer and I are done annoyingly since they charged 500 euro to find the problems after the new rack broke again months later on their fault, they fucked up the connector to the main wireloom but didn't seem to feel sorry, so I had a word with the manager and demanded a leniency arrangement(not sure its called that way) to only pay for the parts and not their hours of testing and searching without finding anything. (Stupidity)

So I'm kind of lost, I could change the wishbone and suspension for not that much i hope but it won't be sure it wil fix the problem, autodoc seems to sell Bilstein for not that much and the wishbone brand i would take im not sure on.

I found a small wobble in the right front wheel but it looks like it's only on in the tire and not the rim. I got a spiritlevel and checked for any bents in the lower control arm, measured some things other and I can't find anything, the setback now looks not more than 5mm. maybe I can trow it on my insurance to get it sorted out. All-risk baby.

EDIT: my insurance told me to ask the body repair shop which they are cooperating with to make a taxation. It will cost me 100 euro to claim it and will setback my insurancecost to about 12 euro extra per month extra over the coming 3 years, so a total of about 600 euro (or 500 pound). Only the taxation without repair wil cost about 100 euro too if they can't find any real damage, so that's on my check. I just can't image the steering rack broke.

Replace the front shocks. The torsion bar connects to the shocks as well. Mine also felt loose and would just go into a direction if not paining attention. Since replacement, all of that is gone. Feels so much better on the road.

Do you have a lot of torque steer? A quick indication is torque steer, if yes, then replace.
