[4" Front Drop Cv Joint Problem On 4x4]

Hello,

 

Purchased McGaughys 2" drop spindles. I want to lower the front about 4 inches. Have read that anything over 2" will cause CV joint binding/damage. What is the cheapest solution to the CV joint angle problem? Raise the front differential? Thanks.

[Pcm Pin 33 And 42]

Hello,

 

Trying to do an electric fan conversion. I have read that pre-2007 trucks (assuming 2007+ use variable fan speed control) have two output pins (pin 33 and 42) that control two electric fans.

From what I have read, most people use pin 42 only, why? Can anyone explain the functions of pin 33 and 42? Does only one pin turn on the fan when A/C is on? Does the PCM turn off the fans when a certain vehicle speed is reached?

I know that 94-96 B-body vehicles have two pins and fan 1 turns on when temperature is 225F and or A/C head pressure is above 189psi. Fan 2 turns on when temperature is 232F and A/C 240psi. Both fans do not come on when vehicle speed is above 45 mph or so. Does the same hold for pre-2007 trucks? Thank you.
