Have a 90 LS400 that runs so smooth that you wouldn't even know the engine was running but for a real annoying squeak that i've determined is coming the the power steering pump..pulley i assume..what can be done about this? Belt only has several thousand miles on it. Thanks!

 

Could the bearings in the PS pump pulley be shot? Should i wait for something worse to occur or plan on replacing the pump now?

 

Change the fluid first and see if it quiets down, mine did after flushing the system.

 

Ok..should i have the PS system professionally flushed? What do you recommend to refill with?

 

quite easy to do, just pull out bottom hose and hook up to an empty gallon jug with a plastic clear pipe. start engine and pour dexron fluid until fluid run bright red. You need 2 people for this job. One to turn the steering L to R as you pour in the liquid. Raise car to avoid stressing the mechanism and avoid flat spotting your tyre.

 

I'll proly check the tutorial on this...Should i use synthetic..Redline..Amsoil?

 

Any Dexron III fluid will do fine, so take your pick. I personally use Mobil 1 synthetic ATF in my power steering since it's cheap (compared to other synthetics) and good.

 

Approx how much PS fluid will i need to complete the flush?

 

www.lexls.com , should solve your problems

 

Is it ok to mix Dextron ATF fluid (any brand) to the stuff you have in there, in order to top it off? Buy at Toyota Dealer or any parts store is ok?

 

as long as it isnt leaking, it's prolly DIII you have in there as it is. if you want to be **** about it you can flush it down with synthetic Dexron III spec fluid, but honestly any DIII fluid will work fine. medium grade from a parts place will work fine.

 

Thanks PD, not it isn't leaking. Appreciate it.
