Determining Flywheel

Can I determine from the access panel what flywheel/clutch is in my truck? More specific the difference between dual mass and single?

Yea if its dual mass grab the pressure plate and it should spin without the motor turning over shou spin fairley easy

The DMFW has the dampening springs in the flywheel itself (unlike a normal SMFW that has the dampening springs in the clutch disk). The DMFW will also have two masses that can be counter-rotated against each other, but only for about 5/8" or so (measured at the outer rim. Cheers!

I will check this tonight. Truck is kinda jerking (especially backing into the driveway which is a small incline) sounds like everything under the truck is banging around and if I don't press the clutch back in seems like it would thrash the truck around pretty good. It does it if starting in 2nd gear for example on a slight inclilne, feels like the truck isn't just hooking up.. Hard to explain..

When my dual mass was on its last leg it would rattle and was deafaning. It was louder than the motor.

truck seems alot better in forward gears, but still if I let off the pedal on the freeway for example, it clunks and jolts the truck.. anyone ever had a broken motor mount?
