You may need a very think metal shim to eliminate the excess play. Basically, an ultra thin washer.

yes thank you , brass washer maybe the solution but the play tolerance is also with the bolt insert

they are piece of shit customer service its all can say , i do mecanic since a decade on atv and car and don’t tell me to use grease to remove play wtf!

just imagine you bough a brand new car at the dealer to fix a loose defect on your suspension and they tell you it should be good with some grease !!! same when a ball joint is loose on a car or spindle it cause the wheel to move side way and its what happen with this piece of shit design trucks,
i am a diy guys like all of you, and i tough will be nice to buy ready to ride board but i regret my decision of buying this , the remote also is very cheap feel and not showing me the mileage ,

I would not consider THAT a POS customer service response, it can…will get worst. Is the other side like that too? Can you identify the specific part/s of that complicated mechanism that is causing the fraction of millimeter difference?

Based on my limited experience, a mismatch of 0.1 - 0.2mm can cause movement like that.

Have you used a pair of calipers to measure the two pieces to see what the difference is?

even the shocks mount are mounted loose i mesured 0.30 mm

mesured with feeler gauge is 0.20mm , btw i have 35 years experience with mecanic and i can say this suspension truck need upgraded , they use o-ring for keep metal to metal contact ! so in fews month they will be destroyed ! now my only solution is the shim, and use lot of grease , the sleeve bolt was installed dry!

here another proof i not wrong they add shim washer to the bolt kit ,
