Finally got myself to work on the proportional valve.
Didn't work out what i expected.
Beside having a shorter spring from the ZJ's, the shaft/piston was a hairline bigger.
I'm not sure if i have a bad ZJ's O-rings but it was leaking like a sieve.
I just replaced my XJ's spring with ZJ's......works like a charm.
Took for a test drive, WOW! Braking power has improved by aleast 50%, i strongly recommend replacing with ZJ's spring if and only if when you do a rear disc brake upgrade.

Having some play at the steering gear box.
Video

Sign of a worn out gear box?....Durango Gear box is on my wishlish but i thought i give the adjustment screw a try before spending on a Durango.
Removal of e-fan to access adjustment screw.

Adjustment


Here is a video (courtesy of 612to303)
Cant say there is a world of difference (1/4 turn adjustment) but steering feel a bit tighter now.

If your wheels are turning full both side and is just the steering wheel not centered....look into adjusting your draglink.
Otherwise, it could be your steering gear box/steering shaft or steering gear box/pitman arm being off (if that is someone has replace, rebuilt any of these parts).
Your best bet is to start a thread at OEM to get some better advice.
Wish i could be of more help.

After replacing my distributor/block gasket, i still got some leak, so i thought i give the oil sender elbow connector a try...
(yes, i have no life and i'm always finding stuff to fix
)
Removal of sending unit


Removal of elbow


Cleaned and ready for installation




Installed

Let hope this would eliminate the leak, otherwise i'm gonna replace the head gasket come fall.

Damn you are patient! Very informative. Done a few lifts and it's always fun to read again and again.
When I did my lift, I wish I would have gone as slow and cleaned everything. Bravo!

So one question on the bumper. First off congrats on keeping it in perfect shape
Did you put some sort of rubber trim on the sides?
And for the APN headers how are they holding up? Any difference against the rusted crack ones? (mpg, noise, power) if any
I'm thinking bout investing in those after seeing this thread

I used some door trim on the sides....oh, don't forget the sticker for some "custom" look
.As far as the APN, other than smoothing out the idle i didn't notice much in mpg nor power but bear in mind my stock manifold wasn't really in that of a bad shape except a small little crack.

You might want to consider these and save yourself a few pennies...
