I had the 231 stock in my 87. The BA-10 went to 145K before it took a dirt nap.


33s and 3.07s is not the best combo...32s are marginal, IMO.


With those low miles, your vacuum-activated 4WD might still work. If not, the manual conversion is pretty easy to rig up & well worth the time.

Beachcruiser - So, on that note, with me wanting to run 33's - 35's, does anyone have a recommended gear ratio?

My buddy did the 8.8 convo on his TJ, and is running 4.56. However, I know my set-up is totally different (tranny gears and such) and I'm wondering what someone might recommend to put me in the ballpark. I'm thinking the 4.1 might be just fine for me.

I've always assumed that was pretty accurate. That said I have 4.10s with 31s and my 258 can haul some *** and has neck snapping power despite its problems.

4.10s and pie-cutter 33's with an SOA is the cat's meow for YJ's, man.

35's are a bit bulky and without the extra muscle to turn them it's hard to justify the step up from a tall n skinny 33 in terms of sheer performance.

4.10s will also work for your application of 35s if you go that route.

This hasn't been said yet but a rig that old with so few miles..expect gremlins.

It spent a lot of time just sitting and that means oil didn't get spashed around to prevent interior rust and seals had a chance to take a royal set then harden. Wires sat in one spot and the insulation hardened, now the normal flexing will make them crack.

Nothing epicly bad but there are going to be quite a few little issues you will be chasing at least at first.

Good Luck and congratulations!

Vadslram, you are right on.

Even though it had just been changed I did the oil and filter again. I also swapped out the antifreeze with some fresh. Taking her in a day or so to have tranny, T-case, and differential; fluids changed. All rubber hoses, vacuum hoses, etc seem good and pliable. Not sure if thay may have already been changed...

I will say though, I can tell she was driven some. There is a decent oil sheen on the motor and most of her components under the hood.

One thing that was rather odd to me was looking underneath there is a slight sheen on the bottom side of the tub above the tranny. I've heard the ba-10/5 can blow oil out the vent tube and that it's recommended to raise it, so I'm wondering if that could be my culprit. Anyone heard of this issue?

On a lighter note, I made my first purchase... some new side view mirrors to replace the cracked stock ones. Also, the GF and myself are sneaking away in her this weekend. Gonna take her down to Daulphin Island, AL, take the ferry over to Gulf Shores, and head on down to Destin for a few days of relaxation. Hopefully it's at least sunny/warm enough to get the tops off the doors. If nothing else the girlfriend said I can take her top off!

I haven't said it recently, but THANKS AGAIN for all the info! It is noted and hopefully will help me make the right decisions!

Being that you have the 4.2, 4.10s are correct for 35s, 3.73s for 33s

I have 4.10s and 33s and I don't use 1st (on the street) and wish I had a 6th gear on the highway

Yep, agreed. You and Cayla enjoy the jeep (assuming that's her stocking behind you two)!
