I run the V3 center. Just feels more consistent. I run 10/15/7.

Ok.... so what's wrong with the V2 diffs? I have no problem with the V2 diffs. Just wondering what peoples thoughts are on them.

Spunkysandoval- I know... what's up with the caster play in those upper arms. I've tried shimming them, new arms, etc. Are the mugen uppers any better, I have like 4 sets of Associated uppers. I might try a different hinge pin.

I've had this truck since may 2016, I never had a shock end pull out till 3 weeks ago. I always replace the ends when they pull out. Front droop is at 106mm. I thought it was the lower arms flexing so I replaced them and that worked for 2 races. Yesterday I had another end pull out on the 1st lap. Always front shocks. Only thing different is chrome shafts this season. I thread the end onto the shaft just till it reaches the last thread. I had some viscous crashes last year(1st season w/ rc's) and never had one pull out. Anybody else having this problem w/ shock ends pulling? Oh yea, and I tried the mugen shafts and they bend as well, I guess if the arm flexes enough any shaft will bend.

Try running 104mm of sag. I was having the same issue for a while and when I reset the sag to 104 it fixed it. Also try screwing the end on until it stops instead of to a certain point.

The V3 diff has more volume I believe. I know they have the same gearing as TLR and Mugen's new diffs. They are more consistent.

I've been reading through the different posts on this truggy and am hoping for some clarification. Like some others I am having an issue with grinding / chattering in my diffs primarily under braking and sometimes during hard acceleration. It is more apparent with larger tires too - not surprisingly. I built the diffs per AE's latest recommendations and have shimmed the diff case within the gearbox in addition to adding a shim behind the pinion gear in the box. I continue to get grinding. Is the sound coming from the ring and pinion gears or are my issues most likely within the diff case and the sun/spider gears. Also since it is under braking I'm guessing it is the front diff. If anyone has a solution please share. I like the truggy but this grinding is troublesome. Thanks in advance.

check your front gear box, if the tab that mounts the upper screws is cracked then the diff will slip out of position and grind on you, this happened to me after I lawn darted a landing into the face of a jump, after replacing the gear box, then the grinding went away...



I would also consider upgrading the front bumper from T-Bone Racing to prevent the stock bumper from hitting into sway bar and consequently busting the gear box:

Thanks Bill. I went ahead and pulled both gearboxes and locked the outdrives while trying to turn the pinion. The front gearbox while it didn't looked cracked had a lot of flex which in turn let the ring and pinion skip. Replaced he gearbox and reshimmed everything. Can't test it due to rain but my fingers are crossed.

Does the gearboxes interchange between mugen and associated chassis? Are the bolt patterns the same?

You need to add shims. In total I have 5 shims on each diff. Cleared it right up. As the diffs heat up so do the plastics so they begin to flex more. Adding shims helps keep the pack tight in the case and stop flexing.

Nope. Not even close.

Just an FYI the new 3.1 diffs work really well in the truggy!
