you can but it will be cheaper and safer if you get a reconditioned exchange unit from an accredited steering specialist shop

The lines. you have 2.
high pressure and low pressure. combined, they cost around $400 at dealers but can be found cheaper online.
labor at a shop to replace both lines calls for 2.3 hours, so you will pay their cost per hour of labor.
plus shop fees and tax. (fees cover shop supplies like fluid, gloves, etc)
If the problem is the power steering pump itself, the average cost at shops for the part is $450 (part only) plus 1.6 hours of labor.

if the issue is the steering rack itself, you can find that part online for $350 on average.
If you just let the shop order the steering rack, they may hit you for $1,200-$1,400 just for the part, and labor times for that job is 4.2 hours.

Please note, the link I have attached may notbe the correct part for your toyota. You would have to search for the correct vehicle.
include engine size and other required info like "Toyota camry LE, 2.5L, front wheel drive"
Hope this helps.

Because it needs new shock absorbers?

Unless the rack and pinion gears are slipping (jumping a cog), then try putting oil on the universal joint in the steering column just above the rack & pinion. Two mechanics wanted to change the rack & pinion for $900 or the "Yoke" (whatever that is) but a generous squirt of oil on the U jont fixed the problem for my 2002 Camry!

2002 Toyota Highlander AC refill location?

This violent shaking where you can stop it by holding the steering wheel in my experience is due to a BAD rack and pinion. Replace rack and that will solve this problem. Good Luck and thanks for using FIX YA
