Interchange rack and pinion?

The size of the wheels on the car have nothing to do with the rack and pinion steering other than the wheels are bolted onto the hubs and the hubs connect to the tie rods coming from the steering rack which is neither here nor there. You could have 28-in rims on the car wouldn't be driving anywhere and probably wouldn't be turning the wheel at all and it would look awfully goofy but the rack would stay the same.

 

If these are the from-the-factory wheel sizes, there are differences: turning radius is greater, and stop-to-stop of steering is less, on the model that comes with 17” wheels.

our 2010 Touring came with these wheels and specs, and can be a bit of a boat, in cramped parking lots.

besides these differences, there might be fit issues; I’d stick with a 15” transplant.

 

From the factory, the 15 inch and 17 inch trims come with different steering racks, different brake actuators (because of different stability-control firmware), different power steering ECUs and motors, and different body sheet metal for the rear wheel wells, and those are just the differences I know of.

That doesn't mean there aren't people playing aftermarket mix-n-match.

 

You on Kona??

 

I would imagine it would be a smart thing to put back on the car what you took off or parts that are made to interchange with the parts you took off I mean that would be a about it or if you take the whole rack assembly out of the 17-in wheeled car and set it down on the ground right next to your 15-in wheeled rack and see where he stand I can't imagine that they're going to be any serious angular differences worth that much discussion but I could be wrong I would love to see that I don't have time to go look up the individual parts just to see and I know the individual part will be different oh they make sure that these days. But then when you get the parts out and really take a look at them you see much of nothing and you put that mess in your car and it works fine The 2-in difference in the wheel size doesn't seem like that would change much geometry of the tie rods or any of that and if it did it would seem to be on the outer which are easily changed

 

I have a 17in wheel rack and pinion from a ct200h in my 2010 prius IV. It works. I would not say my car handles like a boat it steers more with less input. My traction control seems to go off more often but not sure if that is the rack or because of my driving style. Only in corners going fast or on U turns. One thing I will say is this is one of the few parts you should buy from the dealer. The others being the brake booster and the cv axles. Maybe wheel bearings too but I have had good luck with mevotech. The rest you can try to find a more budget option.

Edit: The 17 in rack has 2.8 steering wheel turns lock to lock and the 15in has 3.6 turns lock to lock.
