Thanks for the tip! Just picked up a couple of files for 7 bucks at lowes like you said. I should get my mbx8 tomorrow. Now I am prepared !

I saw that the new car has the steering posts keyed into the chassis now. Is this true? The questions however, has this fixed the problem of the chassis screw working out over time? How is the maintenance compared to the old car in this regard? Is it easier to remove the posts?

I did not own the 7, but I have had zero problems with the chassis screw working out on my 8. I have always used a little dab of blue locktight on the posts. The posts are easy to remove, just need to pull off the top steering plate. The HTD diffs can be pulled out super fast. I love working on my MBX8 Eco.

Thanks Slackin.

Ive raced their buggies since the MBX5 and its always been the same problem. You can use all the loctite in the world, and they are still going to work loose. Its been a problem on all my cars, but was happy to see they adjusted it for the new car. Thanks for the help!

I just drove my mbx8 for the first time. I noticed the rear is loose. I ordered some softer springs and brass pistons for it. Just wondering what anyone else has done about this.

I just got on here to ask the exact same question! First time running mine was today also. I'm thinkin of trying 5/4/1, I have 5/5/2 in it. Or changing to regular diffs (not HTD's). Or underdrive in the rear. My MBX7 drives way easier (and faster) with regular diffs and underdrive. I had a AE buggy that was similar in feel to this 8eco, like a 2wd feel. Not liking these HTD diffs!

I'm building my first MBX8 and I have a question. What does the small set screw that screws into the rear wheel hubs do? What exactly is it securing? I screwed it in. I just want to make sure it's in correctly. Thanks.

those little screws are not securing ; they are suposed to be an access to oil the ball bearings

I put the underdrive diff in the rear (42/12) and it was still loose on power and off power.

Are you using the standard setup mate?

HyperMBX7R

All mugen cars need some time (~1 gallon or 15 runs (Eco)) to get a free drivetrain without a loose rear.

I did come across something Adam Drake said that was similar to what you're saying. I didn't realize that you needed to break in new buggys. I am new to offroad and that's why I am in here asking questions. Thanks

Once you tighten everything up when its all bolted down to the chassis the slop mostly goes away at least mine did.
