2500Sub

Posted October 7, 2002

Hey guys, I am experiencing a binding feeling in my rear diff. I am going to change the fluid and see if that helps. I have read about similiar problems due to the lack of using the GM friction modifier. What kind of fluids do you guys use? BTW I have a 99 Model 2500 Series 4x4 Suburban.

Thanks

- Driver side view mirror, not folding closed.
  
  By Patrick Fergy · Posted 14 minutes ago
  
  I just bought a 2015 Silverado Z71.LTZ 5.3, the power Sideview mirror is working properly on the passenger side. However, the driver side does not fold in like the passenger side. I tried it both on the door panel and using the key fob with no luck. Is there any other suggestions what I can try? Thank you in advance.

  2011 GMC Sierra. Had to do some work under the passenger seat. Have no idea what those fancy bolts and nuts are called. Had to take the seat off it's mounts. Somewhat of a commotion. Front nuts are 15mm or 9/16. 9/16 fits a little better. Rear bolts are 7/16 and fit good. Problem with the rear is that they go right through the body and are exposed to the elements. Got them off though.

  Hanging around $4.00 for 87 octane. Diesel is spiking fast, truck stop is $5.94 now. Going to be over $6 soon from the looks of it.

  A custom aluminum or stainless skid plate would look good and cover most of your hitch.

  Correct. It just gives a rough idea of what to expect.
