I use Redline fluid and have 180k on my original pump. It's had 33's on it since I bought it pretty much.

Hydraulic fluid goes to shit after 115*. It really has to be kept cool. There are guys that run that same stuff as shock oil in the off road world, does good for an occasional off roader but it will not last in a truck that hammers through the desert. Proper size shocks play a role there too though.

I still really like the BG stuff. Got it got a few times and made no difference. Lots of guys swear by the redline oil for crawlers with full hydro steering too

Hydraulic oil does not go to shit 115*. 230* is about the max it should see. At 250* the oil still isn't really the issue. The seals and o rings get hard and will fail. A properly functioning and design hydraulic system should operate at about 100* above ambient temperature.

Well I finally got almost two weeks off and got my 4 hours of mowing done and 6 of 8 hours of weed eating wiped out and some other chores caught up.

Trucks getting tore down tomorrow and getting the pump ripped out and doing the driver side manifold while I'm at it and pluming in my second P/S cooler. So I'll have a review of the pump hopefully Saturday, gotta do some spring cleaning while the trucks apart too.

I put that pump in my truck a month ago and feel it has less pressure than my GM one did. My steering got harder opposite of what I needed. Hope you have better luck.

If it doesn't work they will get their pump back, and I'll buy a brand new stock LML pump. I hope it works because I'll be mad as ****, I hate working on shit just to fix it, especially when I paid for something to do what it says.

i'd rather go old school and show up at there door step and play punch In the mouth. lol

That's my favorite option but it will get you 30 days of weekends and about 5500 in bullshit medical bills and "lost wages", crock of shit, oh then it costs another 7 grand to get it expunged, everyone's a badass ass till you show up to call their bluff, every time I've made my point the cops always show up or find me.

But.... might be a little easier going out of state and stirring shit, least take 6 months to a year for the warrant to catch up with ya, lol.

Got pump, new cooler and lines ran, and LML manifold installed today.

Pump ran low on fluid filling cooler and lines-it's growls LOUD. So that tells me the gear is at least larger as they state.

Steering at a standstill is pretty easy (when pump is cold) I've not drove it yet, going on a 85 mile trip in the morning so we shall see. And so far pump is silent.

Cooler line was pretty warm going in, line coming out is cold-truck ran about 30 min at idle and 2k RPM's working wheel and checking for leaks and heat.

I flushed the fluid two more times to make damn sure everything is clean (flushed 3 times prior to pump swap)

And the LML manifold was easy once I got a swivel and slowed down for 30 seconds, idle is deeper (nothing dramatic) but should sound a little more like the old truck.

Took it up the road and worked the steering and did a little burnout, lines were still cool and steers from a stop, what I mean by from a stop is NOT lock to lock, it gets that "catch" still after about a full turn, but bump the brakes and it takes off again.

So all in all I'm happy with it, I'll let you know more after I put a couple hundred miles on it.

Got home and got a service four wheel drive light out of nowhere -B2426???

I've put just over two hundred and fifty miles on since yesterday, drove 140 miles today to work, pump is quiet, steering is great and brakes will lock up finally.

Just pulled into Walmart and tried to cut wheel stopped, it will go about 1/2 turn with the brake pad pushed and if I put it in park with no brakes it goes over a turn.

Pretty happy with the set up overall. The cooler is a transmission cooler of an 08' halfton.

Put another 200 miles on, did a couple intense burn outs and sat in traffic where they usually get hot and still perfect. Gonna flush fluid when I get home just to be on the safe side
