Has any one tried the Posi-Lok system in stead of the Gas Actuator?

Question

I replaced my 4x4 front differential actuator about 4 mos. ago and its gone again. Atleast my light is gone and I have power at the terminals. I have an 88 K1500. Been reading about this posi-lok system that replaces the actuator and wiring with a Fork and Cable system. I guess it gives you something like an old time Choke inside the cab, pull it an inch and it engages the front axles.

I was just wondering if anybody has seen/experienced any problems with this thing as they are wanting 170 dollars for it. But if I got a buy another actuator I'll be already over 170.

Thanks for any input

buy the 98+ electromechanical actuator and adaptor harness from GM... you won't be sorry. I purchased the actuator from

for about

65-70 bucks and the harness was 35, IIRC. I was looking at the same thing when my '88 K2500's actuators went out for the second time. the new actuator engages almost instantly and isn't affected by the cold.

is a Cadillac/Olds dealer in Gainesville, FL, I've used them twice and have been very happy) as there are a few adapter harness p/n's available to make sure you get the right one.
