So glad I've just watched this video. It kinds of explains something that is happening to my reconditioned steering rack. But hard to explain via text. Here goes when it's in the center and if you want to turn left or right you have to push on it real hard. I'm beginning to wonder if the last part of this video is the reason why my steering is hard to turn with to much tention. Thanks for the explanation 👍🏿
So on our 2012 Infiniti G37 RWD we got last august with 81k on it has always had a loose, over assisted feel to the steering. There was some leaking around what appears to be a drain plug on the rack that I cleaned up and tightened. Now the leak is gone, and the steering tighter. Perhaps I need to back off a tad on the nut as it may be both a drain plug and tensioner? Perhaps a gasket is missing is why fluid was leaking, as there was buildup around the nut and also the inner tie rod boot, plus of course the fluid on the ground directly below the nut.
It looks like when you turn the input to the right, the rack would push the wheel to the left (and vise versa) - I know this isn't what actually happens, but when I think about it, and when I look at your demo, it seems the input gear would/is pushing the wheel in the opposite direction as the input turn. Can you explain how the the input direction translates to the wheels turning in that same direction?
The steering knuckle on the hub where the tie-rod mounts is located behind the axle (axis of wheel rotation). So, when the steering wheel is turned to the right, the rack pushes on the left tie-rod, which causes the back of the left wheel to move outwards (and thereby the front of the left wheel to move inwards), steering the vehicle to the right.
Is there a seal at the end near the gear box on the rack gear? I have a leak at the end near the gear box where the teeth are on the rack gear. It’s not a major leak but the boot is wet. I took the boot off and I didn’t see any fluid dripping out, I’m trying to figure out if there is a seal or which seal might be wearing out at the end near the gear box.
