U need a front wheet alignment
front end alignment
Caster, camber and toe are part of the front end and steering alignment.
Have the wheels balanced. Get a 'front end alignment' done on your vehicle.
1 of 2 things or both, alignment or balance.
Have an alignment performed by a shop that specialises in front end work.
Wheel alignments require special equipment, but to do a rough alignment,(such as after replacing steering parts)to get you to the alignment shop, you can measure the back of the front tires at center, and the front of the front tire at center and ensure that the two measurements are the same.Then go straight to the shop. Driving with the alignment out wears tires and can result in loss of control.
Front end alignment
Have the front end checked via a wheel alignment
Right front tire low of air, or front end out of alignment.
There is no adjustment on rack and pinion steering. If you're steering is sloppy or something I suggest you get an alignment and your front end checked.
Take it to a reputable mechanic for a front end alignment, that is how to properly center the steering wheel. Ps. Generally, the steering hub and shafts are splined, so they only go together one way... Good Luck
