Huge steering slop... Is this normal?

[gigisponer]

Hi,

Brand new Blazer K5 build, not run outside yet...
It has huge steering slop, is this normal?
I attached a youtube video to demonstrate.

Look closely at the output shaft of the steering servo. The housing is known to crack and allow side to side play of the shaft which then allows steering play like you've got. I see all of your linkage moving with the wheel all the way to the servo. So either the pitman arm(servo horn) is loose on the shaft or the shaft itself has play in the plastic housing. The stock servo is a weak point. Mine cracked after some use but honestly may have been cracked from new but took me a while to notice it. You can run it like that until you want to replace it with a better servo.

It's probably the stock Spektrum steering servo. Mine got sloppy pretty quick so I replaced it with a HiTec hi torque, ball bearing, metal gear servo

Well, yes, the servo is the culprit in part for the slop, but holding the servo arm with my hand, the remaining slop is way too high... I observed some in the bearing housing where the CVD passes (as can be seen in the video on vertical tilting the wheel)... The rest must be in the ball ends. Upgrading the C-hubs will remove some of the slop?

The only time I've had slop at the wheel was when I didn't tighten the wheel nut completely. Check that. I've got some serious hours of rugged rock climbing on my truck and have zero slop at the spindle to c-hub pivot. Either they left out the bushings there or your wheel nuts are a bit loose. I just checked mine and you definately have some excessive play. Just gotta pinpoint it.

I'm still running stock C-hubs, knuckles and CVDs. After 15 months, I also have no slop.

Well, I tightened the screws around the bushings on the C-hub (also checked again the assembly against the manual), and that fixed the way the truck handles on the carpet... No more wobbly wheels. There still is some slop remaining, but with little to no impact on the way it handles - and that is the important part

Thank you for your help guys, great community around here!

Glad that you got it fixed and thanks for the update!
