458 Catastraphic failure of steering rack

Before you test this steering rack, it might be an idea to look at the power steering pump to check it is not putting too much pressure out at end of stroke. When the lock is full on, you would think there would be something to unload the assisting pressure, my thinking being a sudden seal failure that bad has to have a cause.
My RAV4 power steering changes tone when on full lock as if a relief valve is lifting. in the past it would not supply any pressure sometimes when the engine was started, but if you switched off and restarted it was fine for months, in the end we changed the fluid and no more issues- so the pump did have a loading and unloaded state.

 

I was thinking the same. These damn drama queens. Like a bunch of girls around here. Click bait.

 

and there you go.......

 

Excellent diy

 

do you have the actual sizes of all 4 seals?

thanks in advance

 

If you can please and thanks again

 

Again great job and well presented even if it scares me, love that pipe wrench! Also, really liking that complex mathematical worksheet the seals were on.

 

Thanks for the excellent photos and description! Great job.

I also like the BA pipe wrench and the ingenuity

 

Thanks a lot and keep it up

 

Great write up and photos. My contribution for this could be the two bearings on the pinion shaft. Lower one at the pinion end NTN 6001, and upper one by the universal joint INA F 65769.
