motor mount problems

I have a 2002 Malibu that needs motor mounts. I started off by replacing the hydraulic mount on the front right side of the engine. Stopped the engine rocking for about 20 minutes. Then I replaced the mount on the center, next to the radiator. That was an insert (anchor 2875). Again fixed for a short time then same symptoms.
The old front mount was cracked.
Does anyone know which way the arrow (load) points on the front insert mount?
I have a feeling the old one spun.

Re: motor mount problems

That mount has to bear the weight of the motor/transaxle and thus the load direction is downward. If the rocking comes and goes, there may be something else going on. What symptoms led you to the motor mounts?

Re: motor mount problems

The symptoms are a clunk when going from neutral to drive or neutral to reverse. The engine rocks back and forth. I replaced the hydraulic front right mount first. That slowed down the clunk and smoothed out the roll for a short time. Is it possible that that mount is defective and when it heats up, it looses its dampening effect?
Getting back to the front insert, I have the arrow pointing straight up, thinking the load exerts a downward force. Is this correct?

Re: motor mount problems

Is this on the Ecotec or the V6?

Also, check the transaxle mounts... they may also need replacing.

Re: motor mount problems

The engine mount strut is more for vibration. On the front mount, the arrow should ideally point down. However, like RaineMan said, the rear transaxle mount is probably shot, especially since the front one was torn.

Re: motor mount problems

Thanks for the info on the arrow. I redid the job and pointed the arrow down. Still clunks.
I replaced the front mount, the left hydraulic mount. The rear mount looks tough to get out. I might farm that out.
Is it possible there is a trans. problem instead? The engine clunks when going from park to drive, then shifts hard, but doesn't slip when accelerating.
The engine light is on, but has been for years.(Different issue I think)

Re: motor mount problems

Hey Chuck172,

Did you ever replace the Rear Left Transmission Mount? I already have the replacement, just trying to get some advice before I do it.

Thanks in advance.

Re: motor mount problems

I have that problem too, but the dealer said it was a 19 hour job and sometimes it cracks the tranny or motor, I can't remember which, but I don't think they can even tell until they take the engine out. He said to junk it.

Re: motor mount problems

A motor mount R&R that damages the case? Sounds like inept "technicians" to me! 19 hours for a mount? I wonder if you have to pay for the vaseline as well...

I would find someplace else to work on my car if I was given an answer like that. I would not even trust those guys to wash my windows.
