new photos:

it is so muddy out at the 4x4 park since we're in the middle of the spring melt. Streams of water are flowing down every hill. Even the access roads are nearly impassible let alone the trails.







A fire hose is a wonderful thing!











here is my new motor:

that's probably the last time you'll see that motor looking all nice and shiny and pretty!!!

looks too nice to put it in that beast. I think you should just keep the old not so duramax in there 'till she blows. Maybe strap a bigass nawz bottle on her, just to speed along the inevitable.

As fun as it would be to watch a motor self destruct, the month of march is an excellent time for me to do upgrades to the truck. The Mounds, which is my local 4x4 park is closed until may 15th, and the sand dunes state park opens april 1st. So i have about 2 weeks in which i have no-place to take the truck.

here's a question for the smart 4x4 people out there.....

is there much of a disadvantage to having little or no articulation if a guy has lockers all the way around? We're considering getting rid of the rear air suspension and putting the steel bars back in place of the shocks.....

Ever take apart a GM IFS axle?

I spent hours yesterday trying to figure out how to remove the carrier from the axle. I had removed both cv shafts, split the case open, but was unable to remove the carrier.

I beat on it with a hammer, pried with a crow bar, turned it, jiggled it, turned it, and tried several other combinations without any success.

Just days before we did the rear IFS axle on the same truck and had no problems, the carrier pretty much fell right out. The rear is a 98, front is a 90.

I thought there may be a pin inside keeping the carrier from beign removed, or C-clips somehow attached to the axle shaft(s) After struggling for a LONG time i finally called my brother in law who is a mechanic by trade. He gave me the secret. I went back outside and within 2 minutes had the carrier on the ground and started welding the spiders.

looks kind of like this.....only sideways. I didnt take any photos of my setup. (below is actually a camaro or something....rear axle )

Well...the ultimate goal of the flexy suspension certainly is to keep tires on the ground so you maintain traction. You will have the advantage since you will be all locked up. The makers of the Aussie Locker actually recommend putting the locker in the front end of an IFS rig to compensate for the lack of articulation. It would make sense to me.

Ah but there is more...The articulation makes the vehicle more stable. Basically you just have less mass moving around back and forth affecting the center of gravity. I'm sure yoiu can learn to compensate for that by driving technique.

The last advantage of the articulation is that it will keep parts alive longer. Locked or unlocked, keeping all four tires on the ground will help keep stresses evened out. With a tire picked up, the other axleshaft has to take all the torque. I would worry a little about strength with those big tires and a welded diff, but as long as you're careful, things should last. A CV joint is stronger than a regular carden style u-joint in the straight ahead position. They are weaker once you turn the wheel. Basically, try and avoid hammering the stupid pedal with the wheels turned, especially if one is in the air and I think it might survive.

I was under the impression that an inferior front suspension actually gave you greater articulation than a solid axle?

Or does it just ride nicer on the street?

Just rides nicer on the street. On my trail rig, I can lift one tire 35-36" before I lift another one. And I am locked front and rear.

It's really just a matter of physics. You need long locating links to have lots of travel. Radius arms, a 4 link, leafspings, etc give you this. Long-short arm IFS is limited to arm length by...well....the engine. Typical IFS arrangements only have 7 inches of travel and 5 of that is actually usable. The exception would be the radius arm twin traction beam style IFS that Ford used. It allows for insane travel, even with 4wd. Combind that with an engine that sits well back in the frame and you can see why that suspension works so well for Baja rigs.

Onroad the LSA style IFS is supreme because is able to have the optimal caster, camber, and toe at any given tire position just by altering the length and angles of the links.

i suppose my thought on lack of suspension with lockers is that if one tire is in the air, the tire on the ground now has twice as much force pushing it into the ground which would provide better traction. The more i think about it, the more i realize a vehicle with lots of travel is much less likely to tip over when climbing an obsticle. I just wanted to see what peoples thoughts were....

The lockers work great! Got the new motor install done today and she purrrrrs like a kitten. Now i need to find a place to take her. The local 4x4 park is closed until may 15.

There are a few things to finish up. I want to redo some of my electrical, find a suitable hood latch, pad the rollcage (banged my head 1 too many times) and there's a few other minor odd and ends. Found out the hard way that i accidentally sliced a hole in the rubber brake line while removeing the front sway bar. GRRRR! And don't forget the winch! One of the local junk yards has a wrecker with hydraulic winches on it. I've been meaning to stop by and see what one of those would cost.
