Now time to prep the ZJ bottle. Here is a pic of the ZJ and WJ bottle beside eachother. For the ZJ bottle, unscrew both pumps. For the WJ bottle, pull out each pump. Clean the black filter on the WJ pump (saw a bunch of slime in mine in the 2nd pic below) and then press each WJ pump snugly into the the bottom of the ZJ pump (put the white pump in the back and the black pump in the front under where the filler opening is).
Now, trim this hard plastic off around the wires to give more space below the bottle for the pumps. Cut all of the hard plastic that sticks up ninety degrees. Snips or dremmel work. Careful not to cut into any wires. Since there are water connectors above, you may want to cover these wires with something like electrical tape. I didn't.
Now test fit your bottle until you get it right. When it is right, drill two holes for screws. Try to get the bottle below the level of where the hood closes. You can do it, but it will be tight. Then install the connectors, tubing, and 2 screws. I did not have a 3rd hole for the level sensor so left it out. This won't bother me as I don't care about a warning for low washer fluid. Without the sensor, you don't get any codes or warning, so I zip tied the original sensor connector away.
Add washer fluid, test system and enjoy. Note - I did experience less flow to my front washer - I think I pinched a hose underneath, but it's not too bad. Also, you will hear the pumps are very loud now that they are close to you (you could barely hear them before).
Did fluids to transfer case, front and rear differential, added solid dana 30 diff cover and lubelocker gasket. Changed the oil (mobile1 10w30) and put on my wheel spacers (1.5" rough country from jf member). I rub in at full reverse left turn on front of front tires- trimmed a litte off inside of bumper and no more rubbing- now off to the desert to wheel.
Follow-up on the diff fluid change. I would not do the royal purple and molar friction modifier. Because the royal purple already has friction modifier, adding more means the LSD doesn't work as efficiently. So.. Use royal purple and if you hear the diff chattering when turning, add a little friction modifier at a time until it stops chattering. Or add the diff fluid with no friction modifier and the recommended amount from Chrysler- you'll need three of the small bottles all together total for front and rear.
Hey bud thanks for the washer bottle write up! going to do this soon
Hope it helps or inspires- alwayshi, have you done yours yet? There are already good write ups I based my install on, but they weren't as detailed, so hoping this pushes people over the edge to buy the $20 zj bottle and tackle this easy, satisfactory mod.
