Re-install it exactly as you're supposed to and then take a piece of shrink tubing and place it over the joint and shrink it well. Too large a pice and the edges will be wrinkled so I used a piece of tube that was just too small to fit over the joint and then took my needle nose pliers and stretched it just enough to allow me to work it into position, then hit it with a flame and sliced off the excess. The smaller diameter tubing shrinks all the way down around the sides without wrinkling and you can't notice it.

If you give me another week or 2 I might be able to snap a pic of it for you. LOL

We just landed a new client (many NFL Players wear their apparel under their unis) and the scope of work is totally NOT what they assured us it would be. It's actually more than 5 times the amount of work! The due date is just around the corner and some of us haven't slept much in the last 3 weeks.
Did only put the shrink tubing over the part where the cva retainer clip fits around?

CVD= Constant Velocity Drive...manufactured by MIP. The CVA's are already tapped. I always run CVD's...they are a little smaller and lighter...and they do NOT hit the rear arm cross brace nearly as much. Mechanical traction is the same too.
Is the "grub screw" the same one that is used on pinion gears? Not sure what grub screw look like and what size will fit in cva. Thanks

Since the original CVA's don't have a groove that would not work very well and it would slip off. You need to go past it on both sides so the shrink tubing follows down the taper on both sides as that will hold it in position without the possibility of it ever moving.

Just googled it really quickly and came across this: http://www.rcshortcourse.com/forum/t...p-cvd-why.html

Scroll down a bit and click on the image and then move on to the 2nd image as it has better detail. That is exactly how it should look.

? My buggy is turning good left but on right turns I'm sliding the front the o ly way to get it to turn good right is to let it roll around the corner but if I just barely give it throttle the noise Of my car slides out to the wall any suggestions.
I am running the big bore shocks
Front 32.5 w. Oil brown springs 2 limiters 1.6 pistons
Rear 27.5 green springs 1 limiter 1.6 pistons
front shock tower under ball stud 2 mm inside
2mm bump steer
In side steering block
Rear I have shaved brace with 1 mm under inside
I run the plastic b44 rear hubs
I also run avid steering rack
Any help to help the noise from sliding would be appreciated.
Tires I was running front rebars and rear gigabites

If your turn buckles are perfectly even left to right make sure you have the right amount of tow out and proper amount of Negative Camber first. If you do, swap out your inner washers to 1mm and readjust camber and see where you're at.

I tend to eyeball it for my tow out and then adjust camber using the tool.

Will try that in the morning thanks

Is it worth upgrading the bellcrank? Which model, Jconcepts or Avid?

It is. The b4.1 was made out of the newer and more flexible plastic. The newer +8 chassis is made from the original plastic which is stiffer.

Yes. All the +8 chassis are made from the same material.
