4 wheel drive fix

I own an '89 wrangler the four wheel drive went on me this winter. I jacked it up and everything was spinning except the wheels so I think it's narrowed down to the four wheel drive vacuum actuator.

It looks like something's missing right here any thoughts? It would be much appreciated

It's an '89 is there anything I can do just to make that connection there? Or do I need to replace the whole thing

You can open the CAD and lock the fork over in 4wd so that it stays there. You might need to get your front drive shaft balanced though

That would put more wear on the tires than I would want if the wheels were locked together

The wheels wont be locked together, just the two piece passenger axle. The diff is still open if its stock

So would it put more wear on my tires though when I'm not using four wheel drive?

Nope. the front tires will be free wheeling independently while in 2X. I locked my shaft over and no issues at all. I am going chromo in the d30 so it's all coming out though.

I wondered why the baseball kept getting bigger and bigger....then it hit me!

As grandboost98 stated, the only downside to this method is that you may need to have your front driveshaft balanced. A lot of guys do this, or swap in solid TJ shafts. its a good solution to a pesky problem.

Definitely gotta go topless Saturday!

You may want to order a new fork if you're not going to swap in one piece shafts anytime soon. If there's that much rust outside, there's bound to be wear inside. Its only $15 with shipping.
