is a rack and pinion the same as the cv shaft?

Question

I had my rack and pinion replaced and now my cv boots are leaking. After looking a photos of the rack and pinion it looks like it also includes the cv shaft and boots.

Answer 1

No.



The "rack" is a bar of metal made into a flat, narrow, long gear. The Pinion is the pine-cone (thus the name) shaped gear at the end of the steering wheel shaft.



turning the steering wheel, turns the pinion, which moves the rack side-to-side, which is linked to the wheels so you can turn corners.



Constant velocity shafts (CV) are the axles+flexable joints that drive a front-wheel, and some 4 wheel drive cars (and rear transmission, rear drive cars including the Classic VW Beetle (1965 and newer)).

Answer 2

Not the same at all. The steering rack does have rubber bellows on it however which to the casual observer may be confused for the CV joint boots.

Answer 3

they are different, the CV joints let the wheels turn to steer the car, and the rack and pinion

causes them to turn.

Answer 4

Not same.



R&P is to steering the wheels(move left and right).

CV axles is to drive the wheels(spin the wheel).
