Power Steering problems (whining pump)

I would flush it anyways if the fluid was still that crappy color or your just going to have problems again sooner than later.....

 

I'm in the same boat. Here is what i have learned when you buy a pump it doesn't come with a resevoir so you use the one that was on the old pump, the resevoir has a very small screen in the bottom the becomes clogged and starves the pump of fluid. Until this is corected it will continue to trash new pumps. Removed the screen and put a inline filter on the return hose mainly because a new resevoir from toyota is about $185. Hope this helps

 

bro you replied to a thread from 2009, but welcome to TW

 

Have had the pump replaced twice. Whining in pump in the morning while truck is at idle. If i drive it or leave it set for 5 minutes then shuit off restart noise goes away. Im taking your suggestion about the screen and in line filter to my garage this week. Will let you know how it turns out

 

Mechanic found reservoir almost completly clogged off at the screen in the bottom.Its setting overnight in a parts washer to get rid of the crud

 

MY TOYOTA IS DOING THE SAME THING [WINING NOISE ] IVE REPLACED THE PUMP 2 TIMES AN STILL HAVE THE NOISE BUT THE NOISE GOES AWAY AFTER I HAVE DROVE IT AWHILE I GUESS COUSE IT GETS WARM I DID NOTICE THE VACCUM VALVE SWITCH WAS BROKE BUT I GOT A NEW ONE AN I STILL HAVE THE NOISE DO YOU HAVE ANY IDEAS FOR ME ?

 

Mine has whined for a long time; started about 2 years after I bought it new.

I'm going to check that screen in the reservoir now.

This forum is a great resource for info & help.

 

Found after second pump replacement at the garage the reservoir was the problem. I didnt know it wasnt part of the pump replacement. Clean the screen at the bottom my issue went away.

 

After replacing ps pump I still had whining and after repeated attempts at flushing and bleeding to no avail I pulled reservoir off and removed top to find the fine mesch screen almost completely plugged after 265k mi. of use. cleaned and blow dried, reassembled- worked like a new one- quiet.

 

how do you find this screen?

 

so glad I found this thread! same issue here, went pokin' around in the PS resevoir, what's the easiest way to get the screen out?

 

just stick a screw driver down in the bowl an twist a hole in the screen this is what i did an it fixed my problem.

 

Does this sound like a high pitch whine, or a moan? I think my ps is doing this when its cold, but all goes away after the truck is warmed up. Its really hard to pinpoint this sound.

 

I have a 09 trd and it makes a winning noise as well. Does anyone know if they have screens in the resivoir ? Also has anyone with 09 had any issues with this problem?
