Bad Supercharger

[DustinBjug]

I have a 1999 grand prix gtp, and ive been told that there's a bearing going bad in the supercharger snout and i was wondering if it would be cheaper to rebuild it or just to buy a new/used one off of ebay

 

[Bluemagic]

You've been told? Does it sound like rocks rumbling around In the snout?

 

[gtpeddie]

It is probably your coupler, cheap and easy fix

Eaton - EATON Replacement Coupler #ETN-30858

 

[DustinBjug]

Yeah

 

[DustinBjug]

How would i find out whether it is or not?

More than likely its the coupler. Take it apart and see if the holes are oblong, they should be a perfect circle.

if it isnt the coupler and is one of the bearings consider looking at upgrading to a GenV M90 instead of buying another Gen3. Thats what I did when my bearings went out in mine. Good excuse to upgrade. This is asuming you have mods or want more performance anyway.

Easiest way to confirm a bad coupler is to take the belt of the supercharger and with your hand check for play.

Is it bad/dangerous for me to drive my car if the coupler/bearing is going bad?

 

[Kolton Lock]

Not if you disconnect the supercharger belt. But its an easy fix so why not do it?

If the bearings are bad, its already boned.

If its just the coupler, you can still drive it, wont do anything bad unless in a freak case the coupler breaks apart.

Been told by whom? What's their experience with the 3800 & s/c's? Like everyone has said, it's probably just the coupler, I had the sound too when I got my GTP.

Its a $30 fix... To change the snout oil and the coupler. Go for it, will take about an hour to do. Worst thing is you wasted $30 and an hour of your time, best thing is you saved big $$$
