If you're talking about the slipper pads, I think so but I'd have to double check. Seems like i can see the whole shaft wobble though. Might have to hit up AE for a replacement since this thing is brand new.

My b4.1 is much louder than my 2wd short course. I still cant figure out why. No binding, plenty of grease, a new ball diff, and its still loud

check for worn teeth

Noisy drivetrain? Replace the top shaft.

Top shaft is the new topic that must be mentioned every page like big bores. GO!

2 things. 1) use the Xfactory top shaft (part #5210). One piece & machined perfectly true 2) When taking the tranny apart be sure to put the idler gear in the same way it came out. The gears wear to each other from always spinning the same way.

Great advice Chris. I take silver Sharpie and mark the edge of the gears so I know how they came out.

Picking up a b4.1 next week what should I look out for when building it.

This is the one?

Yup. I've edited my post above to include the part #

Replacing the transmission case can sometimes fix it too.

If I have been having ZERO problems with the front bearing in wheel and rear pin in wheel what is the need for 12mm hexes?

huh? you have ZERO problems. ok. so do you need?

How ya been bro? Had the car roacking at Norcal. It didnt matter what BB shocks we used the car was dialed. I'll tell you at the track about the BB testing and results. A guy could be cut into pieces in here if the shared info isn't to someone's liking since I'm not factory I'm pretty sure you have found the same as I have since you're running the Yokomo BB. That makes Kyosho, Losi, Yokomo, and AE that have all been tested on the B4. 3 by me personally. See ya Thursday if you're running. We'll have the new car out running at LSR.

So you can run the JC Mono wheels or any other hex wheel
