Bro phatmonkey,
I'm still wondering if I've stripped the diff shaft keyed area like yours. Do the keyed area you mention is the plastic gear teeth? Do I need to strip open the ball-diff to check for that? Is your stripped ball diff still around? If so, please do take a picture of it and email it to me. A million thank on this so that i can confirm that is my diff are stripped.
Bro geezatec,
both of my front and rear turn the same direction when i turn each of it wheel. Maybe i'll need to lose up the front abit like you mention. As for the rear, i don't think i can losen it, if i do so, the car seem like can't move and carry any high speed. Is this normal?
Bro Mini_Me,
yup, my lock nut rubber is still alright. The diffs nut doesn't lose up itself. The main problem is my front and rear diffs is seem like a direct shaft. No diffs in action at all for now.
Lastly, how to see and check if the diffs are no longer working? When i removed the four screw of the top arms, my gearbox top casing will be removed also, I see a diff in the middle, one big gear on the middle of the diff and one small gear on center. I checked that both gears teeth are alright. Do i have to strip the ball-diffs for further checking? If yes, please do advise no how to check for the problem.
Thank you for sharing... cheers!!
