The Grinding Grizz 94 SSEi problem remains even after replacing all the mounts!

It still sounds like it's coming from the right passenger side. I keep getting these visions of the differential pin scoring the inside of the housing until it finally breaks away.

The sound is only made if accelerating hard from a stop and goes away as soon as the car gets up to about 20 mph or let up on gas pedal.

My solution is not to accelerate hard from a stop but......

Have you checked out the general shape and alignment of the engine cradle?

Hmm, good point John.
What else is there that flexes under torque?

I will give it a check this weekend, when I attempt to solder the EGR tube.


This sure is a comfortable car to drive. I have it this week for work while the Jeep is getting repaired. It uses just as much fuel as the Jeep.
It's actually running really well now with no codes or KR, other than this noise. Crank the stereo and you can't hear it.

Try having someone (you trust) powerbrake the car with the hood popped. You might be able to see what is making the sound, or at least find out where it is coming from when the engine is in a heavy torque situation. I did this once to find out my engine was rocking back far enough for a pulley to make contact with the torque axis mount.

Be very careful, apply the parking brake and chock the wheels just incase.

Thought you said the TA mount fixed the issue???

The new TA mount made the big grinding noise disappear but now there is still a slightly quieter similar noise that replaced it. Same circumstances that make it happen though.

I inspected the TA mount and it is perfect and not contacting metal on metal like the old one did.

Did you front or rear trans mounts suffer new failures?

Symptoms sound like first gear to me. Test that out.

How would one go about testing out first gear?

1st gear is a possibility I suppose.
I had 1st gear go once on the Turbo 350 in my firebird. A tooth chipped. This sound is not near that bad.

Tough to test without taking it apart.

Hi

I think I may have the same problem.......

I'll let you know when I find the fix to my problem


Todd.

My old 95 SLE SC did this same thing. Had all new motor and trans mounts and made no difference. Even had the trans rebuilt twice (for failure) and it still did it.

I checked all the mounts again and they are all perfect.

At least now the growling is flavoured with whine from the CAI.

Noise in 1st gear only.



Sounding more like 1st gear.

Any other tests besides the obvious.

Shifting is fine and other gears are quiet.

No it's definitely groaning in 2nd gear also, under heavy acceleration.

It is more of a groaning noise than a grinding one.

Does it do this when Laura drives it?

Sell it get a 96' SSEi

That's what I do.

Paul, is the same noise that happens when Traction Control is active? Take her out on some ice...

The noise is present with the TC off.

Maybe the traction control is not turning off?

Not what I meant...

When your tires spin, and when the Traction Control engages, there is a distinct groaning noise. Is it the same noise?
