I'm experiencing some slop issues on my EB48.3.
The EB48.4 came up with the fix on this issue but I still have plenty of EB48.3 spare parts that I do not want to upgrade yet.
Problem is in the steering spindle TKR5194.
The bushings (TKR5054A) that goes on top and bottom gets worn over time.
In the spindle (TKR5194) bushing hole where the M4x14mm screw (TKR1445) goes in gets widened and gets worn out to a bigger diameter hole.
After one month, I got an enormous slop on that hole because the bushing did not sit snug to the spindle.
In EB48.4 there is a bearing that goes in instead of bushings which reduce this wear problem.
I have been looking for a bigger bushing. The stock bushing (TKR5054A) is 4mm - Inner Diameter, 6mm - Outer Diameter and 6mm - height.
However with a widened hole, now I need 4mm - inner diameter, 7mm - outer diameter and 6mm height bushings.
If anyone's experiencing this issue and found a solution, please share with me.
Thanks,

Yup, Don't forget Tekno's 50% warranty of broken parts. not sure if worn parts fall into that category or not though.

Yesterday I was replacing some bearings on my center diff and noticed the wear that was happening on my center rear drive shaft. The pins were flattening on one side (the side that has the most contact with outdrive when moving forward). I haven't really looked into it but it made sense at the moment to just flip the shaft around so that the rounder sides would be engaged again while driving.
Has or does anyone else do this? Could it possibly lengthen the life of a drive shaft?
I figured its not going to hurt for at least until a new one arrive.

Although it hasn't happened to me, there's a guy at our track who recently broke the tip on his tool and needed to replace it:

If you find that you really have to crank down on the tool, then I would use a micro torch to heat the pin to make it easier to pop out, also wear gloves and safety goggles just in case something snaps and shards of metal starts flying. I've replaced dozens of pins and haven't had anything snap on me yet, but I've saved hundreds already by replacing pins instead of entire shafts

Yup, that will do fine, when the pins snap, I like to use my pin replacement tool to swap them out:

Can anyone tell me why the springs of choice on the eb48.3 are pink front/red rear. And on the eb48.4 setups the springs of choice seam to be black front/orange rear? What about the eb48.4 is making the pros go lighter in springs? I ask in this thread because I have a .3 and I'm wondering if I should do .4 shock setups.

I had converted to the LF springs on my .3 prior to the .4 being announced. After testing combinations, I was happy with the fact that the springs I settled on for my .3, were the same springs the .4 came with box stock.
What I and most others found, was that whatever color you liked on the .3, when switching to the LF springs, you usually ended up one color lighter on the chart. I grabbed one color lighter, same color, and 1 color darker for testing purposes.

Different springs. The .3 uses the traditional .2\SCT springs, where as the .4 uses the newer LF springs.
