So well ive been trying to work out this power steering issue we found some debree and clogs in the power steering resevoir. I require a new one but lexus has quoted be 580$ for it. That is the most absurd price for what is essentially a metal canister with 2 openings and a mesh filter. If i can get one on the cheap i will otherwise im going to cut the top of, clean it out and reweld it.

I don't know if the power steering assembly includes the reservoir, but some places in the US are selling them around the 200 mark.

 

junk yard!

find it disconnect hoses, and rinse it clean!
