Whiney Taco?

Nope....no hidden superchargers...believe me I checked...twice.

Since day 1 of taking delivery of my 2010 4x4 V6 (about 2 months ago) I've noticed it has a considerable amount of power steering whine to it. First thing I did was check the level, and it was low. I added some PS fluid I had at home, without realizing it takes ATF and not PS fluid. I only put in about an ounce, so I wasn't too worried.

I took it back to CarMax within their 30 day warranty period to take care of a few TSB issues, and I mentioned this to them. They said it was normal, and the PS pump is functioning correctly and not leaking.

Anybody else notice their pump? I have a Gibson cat-back and 33" BFG AT KO's, and I can hear it over those two, no problem. It seems to fluctuate with the RPM as well, obviously because it's a belt driven pump.

Should I be worried? I've heard of people having luck using Lucas Oil PS Stop Leak to quiet down their pumps. Any insight on that?

Thanks in advance guys! Wish it was a supercharger

 

I guess I'm the only one?

 

Nope. Mine is quiet and so is every other Taco I have heard. My old Pontiac was whiney as hell but so are all other GMs. Maybe you should take it to the dealer and get their opinion on it?

 

Tell your Taco to have a Coke and smile and quit it's bitchin and belly-achin

On a more serious note, my PS pump is silent. Doesn't sound like normal operation to me...

 

I have a slight whine but it come from the a/c compressor and it goes away when the a/c is off. My power steering pump is quiet and I haven't heard anybody with that issue. I use to be a service writer years ago for a ford dealership and fords are known to have whinny power steering pumps and it is normal but that is a ford. Is you truck still under warranty? I would let them check it out and if they can't find the problem and later on something happens to the pump it is documented. Keep us posted and let us know how you make out.

 

Thanks for the info. Yeah I owned a Mustang and it sounded the same, but I wasn't worried because Fords are notorious for it. But I was a bit shocked to find out nobody else has this sound.

Unfortunately, my truck is at 55,000 miles so the bumper to bumper warranty is done. Is this covered under the 60,000 mile powertrain warranty? If it is, I'll drop it off my Toyota dealer tomorrow.
