Grindddding Noise,ever Replace A Steering Pump?

[SKperformance]

anyone ever have to replace a bearing on the power steering pump

or a pump on one at all?

mainly the 94 and up ones as the previous 92-93 are probably different

it seems that the last pulley that is way in the back of the engien bay is makeing a horrid noise

it has its own belt from the crank shaft

and it is spinning and grinding at the same time

i also noticed that there aer slight metal shavings

so i am guessing the bearing is worn and causing the pulley wheel to rub on the engine

i was going to cut off the belt but then my coolant would not flrw properly

not too bad since it is a straight highway drive home

but did not want to risk it

so i called lexus and after a while called me back to say there is no flatbeds availabe until 8am

this is at midnight

so i had to sleep over and the tow came this morning to take the car back to my house

as the dealer is closed, since that is where they normally drive the car 2

but since it is a show car and a long weekend they dropped it off at home

first time my car has ever broken and needed a tow ever.

it still drives except for the racket it makes

and i didn't want to drive it home

just to hear bang as the puley lets go spraying my alternator with coolant and frying it

then the pulley damaging the crank and the hood

just to save a few buck and hassel

what a night

anyway

anyone else had a pump go bad or the bearing

and if so got ideas on pricing as i never heard of one being replaced

i think i am going to pay for this damn thing being variable assist on the steering and for it running the fan also

sounds to me like the bearings inside the pully is the problem.isnt there a nut to just take off the pully and replace it?i had this same exact problem with a ford taures and had metal shavings everywere and sounded like hell but just went to the dealer and bought a new pulley and poped it on and was fine.

when i pulled off the old pully it was scraped up and killed on the inside!

im not sure if there is a nut in the middle to take it off or not but i would think so!check it and see and also see if they sell the pulley.hope this helps because that sucks having to get it towed and all!

if the pully dont come off and you have to buy a new pump i imagine you would only be able to take it out by underneath the car.couple bolts and lines i would think!

yah there is a nut on the pulley

but i am wondering if anyone elses es 300

has had a pulley or power steering pump go bad

[SKperformance]

well it seems that the bearings are gone on my pump

i got under it and took the belt off and started the car and omg

it was so quiet again

and i was thinking for the last year or so i needed to get my valves adjusted

but it seems tehy are perfectly in spec by it having no noise

well atleast something good came of this

it seems the dust cover on the bearings behind the pully had moved away from the pump

so dirt and water got inside it

so over the past year or so it has gotten progressivly worse

the race that holds the ball bearings was damaged i am guessing from wear of the bearings getting small as they had no grease in there anymore

and started to bind on the pump

and the race could no longer hold the ball bearings at an equal distance apart

thus causing it to bind and shave the metal apart

unfortunatly there is no kit from lexus to rebuild the pump although the manual shows a full breakdown of all internal parts for disassembly and repair

i hate to buy a new pump for $470

when all i need is a $2 bearing and race to support the pulley

oh well it could have been worse

and cost alot more

i asked the dealer and he said he has never changed on on an es only the 400 engines on thels and such

just my luck

yea that sucks!at least you know how to fix it!maybe buying one from a junk yard and taking the bearings out of that one might work?then again it might hapen again if you do that so maybe your better off getting it new!good luck either way!

Yeah.....That's the name of the game today! Years ago you could get the simplest of parts from dealers, whether it was brushes for a starter motor or bearings for an alternator, etc,etc. It's the same thing with electronic parts in any field. The attitude today is, just throw them out and replace the whole thing. Rebuilding components is a thing of the past because labor costs are so high. I think it stinks....give me the good old days!
