Is anyone else having troubles with the CVD pins coming loose ? I had nothing but trouble on the weekend with mine , every run I had to clean reset the pin and tighten them again, both front and rear , I also broke three of them as well . I'm running modified with a 4.5 t boosted and the track is bumpy technical asphalt with medium grip . The track is known for breaking CVD's as I used to chew up X Ray ECS shaft pins like they were goIng out of fashion . I also built new shafts using all new parts and still had a problem. Other than that the car was awesome just the driver let it down

Did you use lictite on the screw? That helps but you should clean the shafts first as the grees or oil prevents the loctite to work. So clean the shafts then loctite the screw and then oil or grees the shaft.

Flat spot pins are a must but You can use these pin locators from TOP if you have the standard drive shafts.

They do a titanium version if you can find them in stock anywhere. There is also a 3racing version of the same as well. I dont even use grub screws on my shafts anymore and cleaning and relube after a meet is easy.



On another note i put the 1.6 sway bars on the car over the weekend and using the 1.8 inserts could not get the bars free and they would bind up. I shimmed them up at the time and will try and get them working with the 1.6 inserts when i rebuild this week to see if this works but Has anyone else experienced this? I did not have this issue with the 1.4 bars at all. It was frustrating at the time but the set up change was well worth it. We have our state titles coming up this weekend and if i can drive it under the pressure i think ill do alright.

My rear hub broke in half when I was driving on the straight. I think the pin hit the hub in full speed and shattered the hub. So assuring that the pin is well secured is very important, especially when you´re driving modified.

Thanks guys , I'll try grinding a flat as I have a heap of spare pins, I would have done it on the weekend but didn't have a dremel with me. I did loctite the grub screws and cleaned thoroughly beforehand, and left it to dry as well , and the grub screw was still tight in the insert, just the pins worked their way out. I also shattered a rear hub as a result of the pin comming free, so I'm also going to try heat shrinking the cvd as well .

I'm running a 1.5 swaybar in the 1.6 inserts and it moves freely. I tried a 1.6 in the same inserts and it would barely bind.... It worked fine in the 1.8 inserts, so perhaps you just need to lightly sand yours to open them up a hair? The swaybar setup on this car works find but it could be a bit more simple IMO.

The pins in the axles are 10mm I believe.... I kept having issues with them popping out of the stub axle as the couplings wore. I bought the 2x12mm pins and Dremel'd them down to just under 11mm so they barely stick out of the stub axle but not far enough to rub on the knuckle...... I haven't had one malfunction yet! I only occassionally retighten the screw and add grease.

The team durango 2x10mm drive pins with a flat spot are a direct fit( sorry, don't have the part#)
Also a drop of ca on the outside of the heat shrink will help to harden it, for extra security, just apply carefully.

I did once , I put locktite on the screw then I used a shrink wrap around it. Never had any issues again

They don't need to, the servo already floats, just make sure it's not sitting on the chassis. I just put a piece of double stick tape under it, but leave the backing on. Chassis flex seems equal.
