I had the same problem at about the same mileage. Replaced the power steering pump and the start up screaming went away! ( The Jeep's and mine!)

Hi, this sound is most likely coming from the power steering pump. I would first, check the power steering fluid level to see if it is full. if its not at the full mark, add some fluid. If the fluid reservoir is full upon inspection and the whining continues, the pump may be damaged and the pulley on the power steering pump could be slightly out of sync with the pump housing.

The second issue could be belt slippage. i would do a tension check on the drive belt and pulleys as well. make sure there isn't any ware and tare on the belt and make sure the tension is to specs.

Please rate and god bless:)

i had a nissan pickup that would whine in all gears except 4th...it started out with 1st then reverse then went to the rest...solution was new transmission...or rebuild cause the syncronizers or the gears them selves are being chewed up...the new transmission was cheaper then a rebuild. or take it to somewhere that will do free diag on the transmission.

wellyou may have one of a couple of different problems.
1. if you have recently wrked on the brake system you have air in the system and need to bleed it.

2. if you are lossing fluid you have a leak in a line or caliper or rear brake cylnder

3. your Master cylender is going bad

your engine is making noise do to the power boost on the brakes being maxed out
