"High-pitched howling" noise while turning?

[VehiGAZ]

In a 2004 Suzuki Grand Vitara? They'd never believe me!

[VehiGAZ]

So I got my fully-repaired VX back after a full FOUR WEEKS in the shop (!!!), and guess what... the howling noise is still there!!! Ugh!!

The differential actually feels noticeably tighter, believe it or not, but nevertheless, my service writer and I have no idea what to do next.

Well, it looks like I may be joining you on this hunt for the elusive VX moan... I too have been noticing an occassional groan when turning. It only happens once or twice each time I drive, but I want to track it down before it gets worse. I know from previous vehicles that a bad CV Joint will balk during tight turns, and when I had it aligned the other day the mechanic informed me that I have a torn CV boot, so that's the first thing I'm going to look at. I'll keep you posted on what I come up with.

That sounds like what I'm dealing with kpaske. Mine is definitely comingn from the rear, though, so it's probably not the CVJs.

I'm considering bringing it to the other local dealer just to get a different set of eyes and ears on the job.

Add me to the group. My VX is also making this noise.

Appeared/appeared to be a problem in the rear end - but my guess is the problem is with/in the transfer case.

Changed the rear diff fluid changed (additive added) - tires rotated (air pressure checked obviously) .... No difference.

Yup, confirmed that I have another driver's side CV boot tear. That'll be fun to fix... again...

As for the groaning, VehiGaz, mine seems to always occur while entering or exiting a turn, though it doesn't matter whether I'm turning left or right. I'm thinking it's coming from the rear suspension - it sounds like something creaks as the weight of the vehicle shifts in or out of the turn. Possibly a lack of lube somewhere.

[VehiGAZ]

My sound is definitely a rotating-metal-on-metal sound, rather than a creak of the suspension.

Although since I got new shoes on Saturday (Goodyear Wranglers w/ "Silent Armor"), I have not heard the sound again. Hmm... although the new tires should have nothing to do with the sound, I have noticed that the sidewalls are noticeably stiffer on the new tires, enhancing cornering performance, particularlay on turn-in.

Why do I mention this? Because it is at least a possibility that the new tires are keeping the wheel aligned better, reducing the strain on the suspension and axle, thereby eliminating the cause of the noise. That theory sounds pretty thin, I guess, but it would explain things.

Of course, as soon as I post this, it's going to make the sound again. :-)
