TDanny 146 Posted May 20, 2019 Hello Guys, Last week I picked up a Monster Beetle Re-Re. It's really a nice truck but I have no experience with these type of cars at all. I read about a lot in the past few days and based on the lot of topics and videos I made my decision to build it straight from the box and see how long it will last and what will be needed to upgrade in the future. I'm only doing one upgrade and that is shimming the diff gear in the gearbox. I bought the traxxas part number: 1985 shimms. My question is that do I need to put shimz on both side of the diff gear or ponly one needed? THX in advance, Daniel Share this post Link to post Share on other sites
Problemchild 2149 Posted May 23, 2019 (edited) i bought some clamps off a tamiya club member (i did a fitting guide) i'm running a sport tuned the issue is that as power goes into the diff, the diff cogs being angled try and try and push the gearbox apart and then slip JJ Edited May 23, 2019 by Problemchild 1 1 Share this post Link to post Share on other sites
Hobbimaster 190 Posted May 24, 2019 Have a look at the MIP ball diff too, it solved almost all the problems in my MB with the weak gearbox. Just not the drive shaft popping out issue. I had read somewhere MIP may be working on telescoping drive shafts that would make the ORV transmission bullet proof, but no word in quite a while. Share this post Link to post Share on other sites
Problemchild 2149 Posted May 29, 2019 The drive shafts pop out because the way the trailing arm is fitted is a pretty poor design The thing about the ball diff is that it costs as much as half a whole new beetle the clamps are working ok for me i don’t have the tyres glued and they provide almost a slipper clutch effect to protect the gear box I’ve just transferred my brushless set up into the beetle and it’s all holding up ok JJ 1 Share this post Link to post Share on other sites

Should be under $40, but once its in the car, it should be the last diff the MB ever sees. Share this post Link to post Share on other sites
Re-Bugged 10156 Posted June 1, 2019 I put one shim in my Blackfoot (same as a Monster Beetle chassis) and has been fine with a 17.5 brushless in it. Share this post Link to post Share on other sites
