Is this better? It has two differentials, is 4X4. and is more realistic.

That looks good! does the front axle collide with the servo when the suspension is depressed? 

I would also try to support the differential outputs on the rear axle a bit more.

No and I will do that.

I am trying to make Crossover steering drag link to the opposite knuckle http://www.offroaders.com/tech/Steering-Systems.htm I have it mostly made it but it steers good one way but not at all the other way. How do I fix that?

[JJ2]

Can you post a picture? I'm guessing that the drag link has too much of a vertical angle, you want it too be at horizontal as possible to minimize bump steer.

Sorry to be the bearer of bad news, but the rear suspension is far from functional.  I will list the issues, the solution is to redesign it:

• The ball joint can move up and down, which is what you want.  It can also move sideways, so you need stabilizer links, just like in the front.
• Shock #1: the stabilizer links will limit the sideways travel, but it will still exist.  Your shock absorbers can rotate sideways, they also need to rotate parallel to the car frame.  Many builds use this piece on each end of the shock absorber:
  
• Shocks #2: the sideways movement will put stress on one of the shock absorbers.  Leave at least 1 stud between the ball joint section and the shock absorber.
• Shocks #3: as you compress the spring, the black bracket to which the bottom of the shock absorber is attached will want to separate from the frame.  It should sit on top of the frame, or be attached on the side.
• The wheel supports should be beefed up.  They are held by a single axle and will flex (and eventually come apart) quite a bit.

I suggest downloading the instructions for the 9398 chassis - they show how to build strong pendular suspensions.  Yours will be much simpler, but the same principles will still apply.

Good luck.

EDIT: 42005 will probably show you just as much, and it's much simpler.

Thank you and will do.

Your Pitman arm is not long enough, make it a 3L or 2.5L using cams.

Will do.

Amazing! It is so small, yet realistic! I hope that there will possibly be instructions!

I don't do that, but when I take it apart I will take some pics so you can reverse engineer it. If you wanted to know, it is going to be a Jeep JKA Independence.

I am going to stop working on the jeep jk8 right now and make a new MOC. Probably a big slammed truck like this:

[Myers Lego Technic]

To bad! I look forward to the new Moc!

[Lego2016Lego]

Here is the chassis for the slammed truck I am making. It has a dif, 2 wheel drive, 2 L motors, a servo motor and is going to have lights.

Please comment.

[Lego2016Lego]

How do I make it so that the wheel doesn't hit the frame?

You could try using a Virtual Steering Point system , examples below: 

This model by ZBLJ uses that system: @ 1m 54sec

Nico71 has instructions for his one used in the sedan car:

Thank you I will try this.

Small update, I may be making some C-models for the mini dump truck. Note, today I became an Eagle Scout.

[aminnich]

I thought you were done with LEGO and moving onto RC cars? 

[Lego2016Lego]

I am mostly done, but I have that one set so I may still make a little.

[Lego2016Lego]

Here is a C model for the Lego dump truck. It is a monster Hummer. I just have the one dump truck for Legos parts, as I sold the rest.

On the Monster Hummer I added HoG, if you are interested I will post pics if you are not I will not post any.

Hi guys, long time no see! As some of you may know I sold my Lego's over a year ago. I have just got back into it and have been working on a mini crawler.  My part supply is limited so apology's in advance if something seems like it is built weird, it may be because I don't have the parts I need to build it properly. Ok, now that we got all of that out of the way I need some help on this build. if you guys can point me in the right direction to make a small front axle for this that would be great. I don't have any PF but I am trying to make it so if I get some it will be easy in incorporate.

My max size for uploading is 0.1MB so I can not upload photos.

Welcome back.

The axle collection thread might be of some use.
