Sorry about that. The truck is 4WD and has 71,000 miles on it.

There are others here with more 4WD experience than myself, but if it is a constant sound while turning, check the CV joints. If a single clunk or bang type sound, go with idler arm, steering links, or possibly even ball joints. All of the above are pretty obvious when bad. I like to tell folks that if you can grab one wheel and move it without moving the other, something is hinky in the steering!

Normal thing is lower ball joints are bad. Then sometimes its the hubs going if more noise on a turn (jack up to determine). Then the hood hinge bolts can move and pop - gm has a little washer to add that fixes. Could be front stablizer bar mounts also.

00 GMC JIMMY Alternator & Humming Noise Issues

Hello,
Well not 10K goes by with something new, now my battery died on me, fine it was a 2000 GMC jimmy with about 98K on it, so I replace the battery, but there is this humming whirrling sounds coming from the front end, I open the hood, its impossible to pin point due to engine noise, but could it be the ALTERNATOR? When I start it up its running around 12V if i hit the accelerator it shoots up to 14V? as well my odometer digital readout is dims then goes bright when the vehicle is idling, but when im driving with the accelerator pressed its nice and bright, anyone please help, I hate having to pay those GM wrench monkies $80 an hour to tell me everything is fine....

As well everytime I start my 2000 Jimmy the gas tank goes to full, then when I start driving it stablizes a bit but never less than 3/4's? could this fuel sending unit be messed up with the going of the alternator......

If you just replaced the alternator check the 2 pulley up front - the fixed idler and the spring loaded tensioner - all go by 100k so remove the belt and spin them and that should tell you.

If it did not do it before could be. Did you install it yourself and connect the main positive cable before the plug in connector so its polarized right. Is your battery good. 12.6 volts with engine off then 13.5 to 14 at idle from alternator.

Hey there. I have a 1998 Jimmy with the exact same problem. I had the battery replaced about a month ago, then about 2 weeks after that the same humming noise started. Along with the 12V at startup, then going up to 14 when I accelerate. I put on about 170000 miles on it before this started happening. Did you ever figure out what the fix for this was before I plunk down a bunch of $$$$. Thanks
