So this is what i did 2 peaces dom 1 1/4 281 wall one aprox 48 inches, 1 aprex 38 inches.
2- es2234r tre $19.00 each, 1-2233L $23.00. these are 34 ton 1 ton tre depens on who u talk too.
Remove old steering.
taper ream outer becarfull not a lot as you can go to deep.
ream test fit.
until you get it close , mark reamer and do other side. easy does it.
as for the steering box we used stock th rubicon tre.
7/8 x 18 tread same ase the 2234 and 2233 ends.
the 2233L has around hole for tre to go into this also needs reamed. direction i used was front to back. you could do back to front if your s has the room.
This way you can get all the parts you need form any parts store the tre are chevy parts.
I have also saw several post on just buying grand cherokee v8 steeering that is heaver.
ben hanks did the 7/8 treading for me on my last one.
taper reamer was $85.00, but i used it at least 10 times so thats $8.50 per time & still have it.
you can puchase 7/8 right and left hand taps, and drill bit for $210 so this way is expensive for 1 job.
dom $ 7 Plus a foot. i have used almost 20 ft on my projects.
will post pictures
