NP263HD Transfer Case Noise

April 3, 2014 - Author: Courtney Bithell
Question: I have a 2003 GMC Sierra 2500HD with a NP263HD transfer case, at speeds around 55-70 mph it’s making a noise. It did have a pin hole in the case but it was around one of the rubberized bolts I welded that. And now it has a leak out of the rear seal where the drive shaft goes in what do you think is causing the noise? How much for a complete rebuild kit and what all does the rebuild kit come with?

Answer: There are other issues with the rear case that cause problems like this. The snap ring groove in the rear case that retains the output shaft bearing wears causing output shaft end play resulting in bearing failure and noise. Also the transfer case was more then likely ran low on fluid which could have resulted in rear tail bushing wear. It is important to inspect your slip yoke on the drive shaft for wear also. We can help you with all of your parts, a rebuilt or a brand new transfer case.

Saginaw Shifter

March 31, 2014 - Author: bartbarton

I have a 1957 Chevrolet 210 with 350 2WD



Question:  Switching out my 3 speed to a 4 speed Saginaw using Summit Racing 700000 universal Kit. (Transmission not installed came out of a pre 60s car.) The reverse control shaft diagram shows neutral in the front position but only with this being in reverse position to the front, am I able to shift thru all the gears. Did some Saginaw have reverse towards the driver?


This is all dependent on the shifter assembly itself. All of the Saginaw transmissions are the same.  You can see the part we supply for the Saginaw transmission on our site.
