Free-ish steering upgrade

[Moonstonemike]

I figured this out while rebuilding my Granite. There was play in the ackerman arm. As I had already changed the bearings in the diff I noticed that the screw and flange fit perfectly inside the diffs internal 5x8 bearing.

So I drilled out the arm with a 5/16 step drill and pressed in the old (but still good bearings). Now there's no play and it turns smooth.

Probably won't notice any different while driving since there is play everywhere, but for a free mod I'd rather remove slop wherever possible.

After drilling 5/16 just the depth of the bearings (not through).

After bearing pressed in.

I learned quick that step by step removing slop is the best way, like you just did....not everything at once, it never works or you're a Pro lol

Nice mod! I like your idea. Awhile back I got several new stock steering yoke assemblies, servo saver included, for $3/each on Jenny’s, and a few s652 servos for $15/each each. I swap them out every few months or when things get rough. But I may try your idea for fun.

I got a few Ackerman links, I will give this a try too

Best mod on the 6s models. Makes the steering super smooth

Actually, I've found removing slop at those points in the Ackermann is one of the best ways to eliminate steering wobble in the 3s line (along with shimming the steering posts and upgrading/removing slop in the servo link). I just added shims, but a bearing should be even better.

Where do you add shims?

Where do you add shims?

PhillyB_RC made a good video. You may not need the Ackermann shims since you used bearings. Note: His instructions on shimming the steering posts and Ackermann are excellent, but I think his servo link solution is temporary. The plastic servo link wears down quickly. I use the red aluminum link provided here (I don't use the servo saver, only the red link) https://www.amazon.com/Hot-Racing-A...id=1643516336&sprefix=atf48sh02,aps,43&sr=8-2

So I did the mod again on my new Typhon. Only difference is I tried putting the bearing on the topside this time.

Attached a video showing the comparison with and without the bearing. Almost zero pl now.
