Trail trekker question
 

I have a trail trekker turned JK scaler with scale chassis it uses the stock drive shafts which are longer than the micro crawler. My question is when I search on eBay all I can find is micro crawler upgraded drive shafts which won't work, is there a place that sells aftermarket upgraded drive shafts for the trekker or is there a parts list were I can build my own?

Re: Trail trekker question
 

I have yet to see any aftermarket shafts for the Trekker myself, but that's not to say they're not out there. I think many people use the tube from an ink pen to upgrade the drive shafts. MIP may make upgraded ones, but I haven't looked lately.

Edit: This link may give you an idea of how to upgrade your driveline on your own.

if you want to make your own i have used a bic pen tube or 9/32 alumiunum tube. you simply cut the longer part of the shaft in half, glue the stub in 1 end and the rest in the other end

That makes the u-joints the weak link, correct?

Re: Trail trekker question
 

they might be the weakest link anyway. Anytime you add weight,power,or extreme angles it will get worse but In most cases they are fine

Re: Trail trekker question
 

I figured that was the case, I might just buy spare trekker drive shafts just in case.

Re: Trail trekker question
 

The easiest/most cost effective way to keep the shafts together is to pinch the u-joint ears together to keep the "u-joint caps" from shearing off. Slop is what kills the joints (spreaded ears), preventative pinching eliminates that in most cases.

If that's the case Ill just machine out an aluminum ring to fit over the ears like they used to make for the ax10drive shafts.
