4 wheel synchronization

Hi markallenstudio,

Quite often this happens when the differential fluids requires replacement.

The correct type of fluid must be used failing which it would judder when making full turns.

Is the differential fluid change doable by a handy car owner?

Yes, the job can be done easily. Just drain and fill.

Recommended fluid is Honda Dual Pump System Fluid ( DPSP II ) P/N 08200/9002 ) Fluid change capacity is 1.0 liter. ( 1.1 US quart )

How many differentials are there where one would change this fluid?

The front differential is incorporated into the transmission assy. The rear differential is a separate unit which is the source of grating noises when making full turns when fluid quality deteriorates.

Recently took a trip and the car started to buck. Used Injection cleaner seemed to do fine. Got gas in Jolly, TX and about 1hr later started doing the samething but worse. Now it bucks on occasion and the check engine light flashes which never has done before. Please help.

Get a scan done to retrieve the trouble code for the MIL indicating and let me know the EXACT trouble codes.

Most parts stores provides the scanning services.

Ok here is what we found very bad spark plug. 2nd from the right was black, broken and the where the point is the curved part was totally gone. What causes that?

That could be due to misfiring or a bad catalytic converter. What was the trouble code retrieved? It could throw a light on the problem.

This part just got knocked off my vehicle. Can someone tell me what it is and what it is does?

It's a rear differential damper and is designed to keep the vibration down generated by the differential. Please let us know if you need anything else to get the problem fixed.
