I noted 3 problems with my mini-t's wiggley front end. One, the threads weren't long enough on the axle to tighten down the nut enough to make the bearings do their job, a pack of 4mm axle shims from BRP fixed that right up. Two, the stock wheels were either glued by a three year old or someone who didn't care, I went out and got a set of new unglued dirt hawgs and glued them myself, MUCH better, now on top of spinning well from the bearings doing their job and not slipping on the axles, a true set of tires does wonder. The final malfunction is the stock steering assembly, IT SUCKS. There's about 1mm of play in the linkage, the whole thing is just put together bad. I picked up a GPM steering set
http://www.rcxmini.com/product_info.php?cPath=6_10_38&products_id=60 and installed it, now it's one happy camper. Almost no play at all and now I'm not terrified to wrap out my mamba 8000kv, before I'd get high speed jitter which resulted in buying a new chassis pan, twice....damn curbs....
Side note, stay away from the GPM tie rods, they are a very soft aluminum and bend easier than the stock ones, and break much easier, I ended up throwing them away after breaking two while I was installing them, no I have the BRP tie rod set, MUCH better, no more spagetti looking tie rods.
