#405 of 1355 First "real" problem
Dec 20, 2001 (9:34 am)
Finally took my XL-7 in to the dealer to have them diagnose a very quiet "gear noise" that I've been hearing since new. I had mentioned it to them once before (for my free 3K oil change), but I didn't have enough insight into the problem then, and they suggested that I wait to see if it was something that just went away upon futher breakin.
Well, in short, it didn't. I tried switching over the tranny and transfer case to a synthentic lube, and that didn't help (but the transmission shifts noticably smoother). By accident, I discovered that the noise could be made to more-or-less come and go by playing with the transfer lever.
The service manager took it for a ride and came back to tell me that it needed a new transfer case. He seemed pretty sure of the diagnosis too, like he had seen this before. At any rate, I'm waiting for it to arrive so it can be put in, hopefully while I'm still on vacation.
I still love this truck!!! Overall, this is minor, considering the value you get with this vehicle. I still expect this to last me well over 100K, like my last Suzuki did (and I expect is still doing), with proper maintenance. Besides, it's not going to cost me anything, accept a little inconvenience in waiting for it to be installed.
Since I've spent a little time in the dealership lately, I thought I'd mention what I've seen on the 2002s. The back (3rd row) seat seems no different than the one in my 2001, save for the flap they added between the 2nd and 3rd rows (same slight incline). The seat fabric is indeed different (I'm pretty sure someone else mentioned that before). Not better or worse IMHO, just different. Haven't noticed anything else visually.
My mileage has dropped a little lately, probably due to the type of driving I've been doing (less constant highway), and the colder weather (finally got a little snow here yesterday in southern Wisconsin!). I'm averaging around 22.5, from a high of 24 earlier this fall. Coming up on 4K and everything else is just great!
Hope everyone enjoys (or enjoyed) their holidays!
#406 of 1355 Gear Noise
Dec 20, 2001 (8:01 pm)
Thanks for the insight on the gear case problem. I'm at 16,300 on my 2001 touring model. Other than the check engine problem (gas cap missing) that I experenced it seems to be an excellent vehicle.
My vehicle is mostly drivin on smooth surfaces,rarely in cold tempatures, on rough terrain, on mountains, snowy surfaces,mud,rocky surfaces, in fact I have never used my 4 wheel drive.
Is there any specific gear,4x4 high-low pattern, speed,turn,surface,weather,or movement that I can compare my findings with to provide you with information that may verify that this may not be a factory defect, and only a minor malfunction,etc.
Once again, thank you for your comments. This town hall has been very knowledgeable and helpful. I wish you the best! Happy holidays and Happy motoring!
#407 of 1355 Re: Gear Noise
Dec 23, 2001 (6:59 am)
As you might imagine, describing the sound is a little difficult, but I'll try. First, it's very low volume, perhaps less than the wind noise. It's a high pitched whine, or even a ringing, but if you listen closely, you can certainly tell it's gear related, like a "teeth-on-teeth" thing. It might even sound a little like a hissing sound, if you didn't listen closely enough to hear the "buzzing" part.
It's most noticeable over 40 mph, in either 2wd or 4hi (can't really tell in 4lo, too much engine noise) and if I pull the transfer lever toward the back of the driver seat, it quiets down, toward the back of the passenger seat, it gets much more noticeable, and even sounds more like a dry bearing. Also, taking a right hand curve (like an off-ramp) seems to make it go away too. Like I said, I think it's been doing it since I took delivery, and I've only got 4K on it now.
I'm really not concerned that this is indicative of any quality issue for the XL-7s in general. I just figured I'd offer up the news, in case anyone else heard something like this, and like me at first, thought they were being too "picky".
I'll keep everyone posted on the final outcome, but expect my dealer to take good care of this, as they have done up until now. I guess it really pays to give a dealership repeat business...
#408 of 1355 Back up the Truck!
Dec 23, 2001 (7:18 am)
If you've been using it in 4-hi on dry pavement, then there is a good reason why it would be making horrible noises! You can only use 4-hi on snow covered or slick roads or off-road.
My guess is that it's something with the T-case and your dealer can probably fix it.
#409 of 1355 4-hi noise
Dec 24, 2001 (5:09 pm)
What paisan said.
I believe it's common to hear a little bit more noise when you shift into 4-hi since you have more stuff in action. But the noise should not be that significant.
I'm sure that driving on dry hard surfaces would cause problems.
#410 of 1355 Give me a little credit, huh guys?
Dec 25, 2001 (6:12 pm)
The truck was never driven on dry roads in 4hi (or lo for that matter). I'm not a newbie to 4wd, and do know better. The only time it's ever been in 4hi was on wet roads, and that was to see if the noise changed under that condition. 4lo was in my back field (pretty sizable).
But thanks for the "heads-up". If I hadn't been too familiar with 4wd, it might have been news.
Hope everyone had a Merry Christmas. Have a good (and safe) New Year.
#411 of 1355 No problemo
Dec 25, 2001 (7:32 pm)
Just we've seen it here a few times (gas cap un-done = CE light, etc. etc.) where something that is common sense to a "car" person isn't common sense to non "car" people.
#412 of 1355 imadad1st - Noise issue
Dec 26, 2001 (9:45 am)
I had a '93 Suzuki Sidekick that generated the grinding noise at times, almost always in late summer and early fall. I didn't do a lot of offroad driving so didn't use the 4WD frequently during the spring and summer. I found that if I engaged the 4WD and drove for a short distance then took it back out of 4WD the noise would go away. I think it was a lack of using the system that created the noise and after using it for a bit (lubing up all the gears again so to speak), the noise did not return until I had not used the 4WD again for a long period. I used the 4WD all the time in the winter so it was never a problem then. Just my $.02.
#413 of 1355 Synthetic gear oil
Dec 26, 2001 (7:31 pm)
Has anyone used or read about using synthetic oil in the 4WD system? I use Mobil 1 in all my cars and it does a really nice job. My dealer has said that as long as it meets the requirements of suzuki it would not void the warranty. Any thoughts or comments
#414 of 1355 Noise, lube, and other such stuff...
Dec 27, 2001 (5:59 am)
Yeah, I thought of that too, so that's why I took it back in my field for a little 4lo duty. It didn't seem to help. Also, since putting it in and out of 4hi didn't make a difference, I'm inclined to think that the service manager is just hearing something he's heard before on another case or two. At any rate, for such an expensive component, I can't believe they'd be so quick to replace it under warrantee without some reason to believe it's defective. I'll keep you posted on the outcome, whenever it gets taken care of. I called the parts dept. the other day, and because of the holidays, they don't think they'll be seeing the replacement until next week sometime.
In my attempt to solve my apparent transfer case problem, I switched over both my transmission and transfer case to Redline MT-90. Redline was the only company that offered the GL-4 in the weight recommended by Suzuki. If you find any other source, please post it for us. For what it's worth, I think that the transmission shifts as smoothly now that it's (much) colder, as it did when warmer (although, as you already painfully know, it didn't do much for the transfer case issue).
You know, it just occurred to me to point out again that I have the 5-speed manual tranny, not the automatic, as I recall you saying you have. I'd be willing to bet that there's more options out there for a synthetic for that automatic than for my manual.
