Yokomo YZ-2 Bearing Failure...Check Yours!
I've never had an issue with the bearings on my YZ-2 until yesterday's 2WD North East regional. Towards the end of practice I noticed the steering was very vague. I pulled the car off to find one of the bearings in the steering centre link had vanished and the screw had come undone. Luckily I was very kindly lent one otherwise it would have been a disaster. Anyway I've just taken the steering linkage in bits to find the bearing at the bottom of the bell crank has also disintegrated.

Just checked mine and they are not collapsed, but well worn. Just had them on the bearing sizer and they are notchy and the top ones have loads of play. Just pushed one out and it had collapsed really easily.
I think that's caused the play I've noticed the last two meetings. I had the larger size collapse on the steering posts of bmax4 though. Posts bearing size is 5x8x2.5mm. Crank side size is 3x7x3mm Correction: The BMAX4iii steering posts are 8x4x2.5mm, not 8x5x2.5mm as in YZ-2.

Yikes, ill have to have a look at mine, steering still feels nice and smooth, but it is a tight tolerance slipping them over the posts.

Mine were ok last time I checked, which is regularly due to lovely soaking wet grass at regionals.
I will give them another check however as I have them here to be replaced anyway so might just do it. I bought the Avid pack just to discover these 4 bearings were missing. I informed them though and they are now present! Can't fault the Avid bearings, real good quality.

Me too... you can just buy the bearings from MB - £1.50 a pair.

No 4x5x8 bearings listed on my pack of Avid bearings.

If you bought them from MB, give them a call in the morning and they'll send you some out.
