So I have the whining noise going on under the hood & the cars acceleration seems to be very slow lately. I noticed MPGs have dropped as well. Mixed (in Houston traffic) I should be averaging around 15ish & highway 17-18. This already isn't very good but last couple fill ups averaged around 13.5-14.
I am assuming & going to start with changing the idler pulley to address the whining noise. Can anyone link me to the part I need to order?
Would this also impact my acceleration and/or mpgs? What else should I do right now? 02 sensor?
Car currently sits at about 122K miles.
Here is everything that has been done:
New tires at 95K, rotated every 5K since.
K&N air filter at 99K (has not been cleaned since)
New water pump, thermostat/CTS, coolant & transmission flush, serpentine belt, & radiator at 102K miles
New front right wheel bearing at 103K
Spark plugs replaced at 103K
Throttle body cleaned at 103K
New battery (duralast gold) at 120K
I am also due for my next oil change (mobil 1 synthetic) & will be doing that very soon.
I know the biggest issue is I have not done the transfer case fluid or the differential fluids!!!!! I don't ever use the 4wd but yes I know getting these fluids done are very important & a top priority. I have the transfer case fluid sitting at my house just need to do it!
What else should I do or think about doing? I have no codes or lights showing up & other than the recent whining noise & acceleration the truck has been running smoothly & in good shape. Just want to be as proactive as I can in keeping it that way.
Can anyone link me to the correct 02 sensor & idler pulley to order? I prefer to order through amazon if available.
Thanks for the help. You guys have always been my go to when I have any issues/questions and always lead me in the right direction.

- Transfer case fluid
- differential fluids
- idler pulley
- 02 sensor?
- clean air filter
- oil change/filter
- Oil pressure switch/sensor (had this issue once, seems to be bad sensor, have it in the garage just need to do it)
