car pulls to the right when accelarating

Can anyone tell me what the cause is of the following:
when I accelerate the car pulls to the right.
Personally I think something with the drive shafts or differential.
it does not happen when braking.

First thing is to check your tire pressures. You should write down what you have checked at least so we can narrow it down.

Put the rear up in the air and grab each wheel at 6 and 12 and 3 and 9. Shake the wheel, if it moves then you have a bad bushing/ball joint or a loose bolt.

Shop? The test I described you could do yourself with a jack and a stand - although a shop will hopefully be able to provide a better diagnosis.

I'm assuming you did a bolt to stud conversion with spacers - yet I doubt this would cause the issue you're experiencing. You'd get wheel hop or vibrations.

i would get it looked at asap

it could be alignment. does your tire wear evenly fron edge to edge? it could be bad bushng, loose suspension, or wheel bearing.

the self diagnosis to pull on the wheel is a good way to see if bearing or suspension is bad. but i guess you need to fix it professionally anyways so why not take it to a shop to have it looked at. i suggest a specialist or a wheel shop if it's an alignment only.

it could also be a sticking brake caliper causing it to pull on one side

I had the same issue before. What they found out was the RTAB (Rear Tail Arm Bushings) were torn. Had it replaced and it stopped pulling.

This is going to be your problem 99%. If you have any other questions let me know, I'm happy to help.

You bet! So if it turns out to be bad Rtabs you should consider OEM bushings with Polly limiters, or Powerflex red Polly bushings. Everyone one running either seem very happy with the handeling and bushing longevity. Powerflex are easier to install so it may reduce the labor cost a bit if you paying an Indie.

finally i have solved the problem .
the differential was too bad and was the problem that the car pulls to the right when accelerating.
I also change the diff ratio for a 3.91.
My subframe was also torn.
I also renewed my crankshaft bearing
Hope i can drive next week on the nürburgring.
