It's that time of the year! It's time for
KOH!!!
As you guys saw from one of my previous posts I went to King of the Hammers last year for my first time and had an absolute blast. The jeep wasn't done at the time so I wasn't able to take it. This year I'm taking my jeep and I'm STOKED. It's also about that time where a lot of offroad races happen so my buddies rigs are torn down for race prep while mine is finally ready to go

There are a few things I need to tackle before the trip though.
First things first I've had non-stop steering problems every time I hook up my assist ram. When it's installed my steering turns nice and easy at idle. When I try turning fast my steering won't keep up with my wheel input making it feel super unsafe while driving at speed. When I increase rpm it turns slightly faster but nothing very noticable so I kind of ruled out it being a pump flow issue. I figured it was the steering box because I had problems with it since the beginning of the build so I had Redhead rebuild my box with a new housing. After the new housing and ram were installed I ran into the same problem. I contacted Lee Power Steering and have been troubleshooting through email for the last few days. Here's how it went down.
When I swapped my TJ pump to a WJ pump I retained my TJ flow control valve (very common to do for us TJ owners so that we can retain the same output hose fitting size). But here's the big thing I overlooked (for some of you this is probably common knowledge).. refer to the bottom paragraph.
I also found this adapter that PSC makes. This uses an orifice size of .160" which they recommend for higher flow at higher RPMs.
After speaking to Lee Power Steering about my exact steering setup here's what he said:
"The 11/16 is way too big. A 5/32 drill bit will get you to .156 which should be right around 4GPM. That should be just over 1 GPM more than what you currently have.
That will increase GPM at low revs as well. Not as drastic as it does at higher revs, but it will help."
So last night I drilled out the fcv with a 5/32 bit. Here's a pic of before and after. As you can see .036 of a difference is pretty small.
TJ flow control valve:
Before drilling, .120" orifice:
After drilling, .156" orifice:
Reinstalled, properly bled and it definitely made a difference. It's still far from perfect but it feels safe enough to drive at higher speeds along the lakebed.
While I was swapping things out I also swapped out the aluminum AN fittings I was using on my high pressure side. Before starting to build my steering I read that aluminum fittings would've been fine for high pressure PS. This is definitely not the case (refer back to my Rubicon trip).
Here's a new steel adapter I got to convert my flow control valve fitting from the pump to -6. Apparently the aluminum fitting I was using was supposed to come with a compression washer, hence the small leak I had on my last trip

. This one seals with an Oring.
Here's the new high pressure line I made to replace the aluminum crap.
Steering pump is much happier and I can finally use ram assist.
Onto the next item. After my shakedown run, Rubicon trip and a single day of wheeling on Thanksgiving weekend my tires were TRASHED. as stated before I got these tires for like $300 to use as mockups for my build. The date code on these are from 2004 so after 22 years I'd say they're time to retire.
I never look forward to swapping tires on beadlocks but I couldn't wait to get my new stickies mounted.
I didn't use any type of balancing remedy on my old tires and I didn't have any issues with them. With these treps being a soft compound I decided on 10oz balancing beads. We'll see how they do.
Got them all mounted and took her for a rip down the block. Tires feel great, steering feels ok. She's pretty much ready to tackle some dirt.
