Posi Lock Engagement Question

Did the home made posi lock mod this weekend. Pretty simple and straightforward. I am wondering what tips everyone has found to make engaging it as simple as possible. The issue I'm running into is that I have to put it in Neutral, shift into 4 wheel drive, then I have to put it back into drive and touch the gas to get the Jeep rolling a little and try and catch the splines just right to get the collar over to engage.

Does anybody have any tips to make the process easier? My fear is that I'll get stuck sometime in 2 wheel drive and not be able to spin the front wheel at all to line up the splines and get the 4 wheel drive engaged.

Any tips?

It shouldn't matter if you get stuck because the intermediate shaft will still spin eventually lining up with the splines on the outer shaft. Not sure how to make the shifting easier besides just rolling into it.

I have a jeep...and it is modified...I win.

That's how the stock system was designed to work as well. When I still had that set up, I'd shift into 4 hi, then actuate the posi while still moving, never had an issue.

Even with the real posi-lok cable, you have the same issue. I usually throw it in 4WD as soon as i leave the pavement. Sawing the steering wheel ("S" turns) while at a slow roll helps it slide in.
