Fuel gauge needle
On my 99 Suburban, the fuel gauge needle appears to be vibrating and shakes rapidly back and forth about a needle's width or so. Some say it is most likely the sending unit. Comments?

Mine does it too. These gauge clusters fail after a while. Cheap DIY (but PITA) fix.

Mine was doing the same thing replaced fuel pump and sending unit. Stopped it from jumping up and down.

Mine has done it since I got the truck last fall. I would have to guess there is a resistor on the sending unit that must fail.I like you.

Mine too. The voltmeter bounces with the turn signals, too. If I remember right, it's the servo motors on the back of the cluster that go bad - I think there is a post on the site about where/how to replace them, but I won't have time to look until sometime tomorrow.
Good luck to us all...

The stepper motors on the back of the clusters go bad. My gas gauge stopped working completely last year, so I sent my cluster to some guy in Minnesota (through ebay) and for $60, he replaced all of the stepper motors, all of the cluster bulbs and updated the cluster with the newest software. Plus it came with a lifetime warranty, pretty good deal IMO.04 ECSB Custom silver & grey, Soft 8's, BFG KO's, ReadyLift Leveling Kit, Hellwig front sway bar, K&N filter, DeeZee EZ-Down, Rhino liner, Alpine CDE103BT, Rockford 6.5's, 12" V.A.T.

With the 95-99 suburbans usually it is the sending unit that goes out as the ground gets corroded in the tank. The stepper motors do fail in those years but usually it is the sending unit. to be honest if it doesnt bother you let it go till it isnt reading correctly since it requires that you drop the tank.Mike

Thanks for all the comments. Looks like I'll just have to test the sending unit and the stepper motors to find my problem. This Burb is gonna become the wife's daily driver soon, so I wanna get it right.
