After all the good information given to me in my previous thread on the same subject, I decieded to go for an upgrade of the front axle actuator. Digging into it I found out that I needed the new actuator and a spacer/electrical harness kit. The spacer is needed because there is a significant different overall length between the two actuators. So digging even deeper, someone told me that this upgrade was unable to go for on my 1994 Suburban. Anyone who knows for sure that it will work, and where to buy the correct spacer/harness kit if the upgrade is possible on my Sub? Midwayautosupply provide me the actuator but not the harness kit. Thanks a lot in advance.
