Default Yokomo MR4TC SD Steering Vibration Problem

I used the drive train it came with. Stock Solid Axel for the Front/Rear diffs. And a center one way. It vibrates when I turn. On and off the ground. I get allot of heavy steering chatter if I turn and open throttle faster.

I am at odds why...

this cause by the front spool.....when you turn the steering full lock, the UJ will binding thus the wheel will vibrating...

no cure on it except u use diff or oneway....or use double UJ which dont hv for mr4tc SD...try put alittle lubricant on the U Joint to reduce alittle bit of the sound..

I lubed it up heavily with grease. Checked it. The pin and the tiny nut that locks the pin into the CVD was loose.

I fixed it. Put on stock parts.

Tested it out.

Still vibrated wildly. I am starting to wish I had gotten the Cyclone S...

My friend has the RTD(RTR) version MR4TC SD and I have the MR4TC SD Kit Drift Package.

His doesn't chatter and wobble wildly like mine does. I have no idea. I don't want a ball diff or front one way...

Sweep back my front arms? Sorry, I don't understand.

My RTD Yokomo does not have this problem and it's nearly identical.

Default chatter

i just ordered this item from ebay...
http://cgi.ebay.com/ws/eBayISAPI.dll...m=280469767936
i have the bd...i will check if it will fit...i guess proper shimming and changing the bearings will do the job(i don't know yet)...all cars will have this vibration when you're using spool and not having this double jointed cvd's...i will let you know when i receive the item ...

just redue the front end of the car and check what's binding. This chattering will cuase premature wear lubed or not.

Scope out your buddys car and check out his setup

Troubleshoot

I was told the bd5 stuff is different and doesnt fit the bd. Guessing bearing sizes and axle thinkness.

Alot bd's have mixed matched cvd's too nowadays and some others will fit but are to long of a shaft and will bind in the outdrives when the suspension is compresed.

ok boys i installed the universal swing shaft...NO MORE VIBRATION!!!
http://redirectingat.com/?id=42X1295...3D280469767936

first,buy 4 bearings 5x10x3 (boca bearings $2.95 each)...make sure you install the spacer before putting the inner bearing...enlarge the hole on the c-hub(unfortunately you have to do it on all your spares) so it will move freely(side to side and up/down action)...i will post picture tonight if im not busy ...enjoy
