Just to inform you, I took my jimny to a dealer last week. He has inspected it and said all the vacuum hoses to the front hubs are properly connected, all t-case wires are properly connected and he couldn't see any vacuum leak, but he "can't be 100% sure". Just as I was afraid of, he had no idea how to solve my grinding problem. All he could say was: "You have a warranty for next 2,5 years and we have enough time to deal with that, but right now I can't see anything".
I am not sure how long does it take to inspect t-case, hubs and vacuum. My jimny was there less than 3 hours and he said he has changed fastening bolt joint (suzuki recall), inspected all above mentioned parts and cleaned them.
And about my second, banging issue - he payed no attention to that one. I know 4 other jimny owners in my hometown. All of them with elder cars, and none of them having this banging. My brand new car everyone can hear on the street as I pass by. But the dealer said this banging is just "normal jimny banging"! And that was about it! Had to take a day off and drive 400 km. Having this car just about half a year - two different dealers since, and no solution.

A banging noise as you drive around is certainly not normal. Nor is the grinding noise. At least the dealer has ruled out any obvious issues. Are the any Suzuki clubs in your area where you might get advice from other Jimny owners. This is quite difficult to diagnose over the internet.

Somebody on here a while back had auto hub random engaging that was difficult to find the cause, ended up being the vacuum solenoid module thingy. Sorry I don't know the correct term. The unit is mounted between the battery and the chassis

Do you have a transfer case skid Mirko
Also I sugest puting up some pics of your car underbody like for example the exhaust bushes. Photobucket makes posting the pictures easy

I made this comment because the user who had this problem had his mechanic say that hoses and wires etc were all good etc etc, only after many warranty visits to the mechanic did he investigate this unit and that was the problem. It's rarely the cause of a hub issue but if everything else seems fine it needs to be investigated. Just because a mechanic says that everything is fine, doesn't mean he's actually checked everything. There are good mechanics and then there are mechanics who are not so good. I'm not saying he's bad but he may not have done a full analyses.

[zukenutter]

Did the mechanic remove your auto hubs when he inspected? If they are trying to engage randomly while driving there would be signs of it inside, metal flake etc.

[Jezza86]

Think it was a epic doubble post
Mabie ill try pulling mine this arvey.

[zukenutter]

3 day apart double post

[Mirko]

Sorry about double post.
After a visit to the first dealer and a phone call to the second one, I was very sceptic about Suzuki in Croatia. Talked to four different dealers, and 3 of them have never even heared of this grinding noise issue. At least that is what they say. Strange! There are dozens of posts on Internet about grinding on jimny, ford, toyota etc. That was my reason to leave a post on auszookers, beliving that some of you have experienced similar situations and maybe could give me an advice. I don't think that this second dealer (that I visited last week) is ignorant and at least he has inspected something, but was that good enough? I don't think so. My jimny is brand new and obviously there is something wrong. I expected he would ask me to leave a car in his workshop for some time to have a proper look. Instead, he said knocking and banging is normal and payed no attention to my explanations. But, since he was willing to check the vacuum, I didn't want to insist, leaving this issue for some other time. I don't think this grinding would stop soon, but let's wait and see. As it was only occasional it is hard to say is the problem still there or not.

I expected him to have a proper look to all parts that could cause this grinding and banging. I was prepared to leave my car for some time. The problem with Suzuki in Croatia is that they have only small workshops with licenses and with situation like mine, one fells there is nobody to address to. My sister and a friend of mine, both have skoda yeti. They had some minor issues under warranty, too, but Skoda Croatia (volkswagen corporation) had a very professional approach. I am not so sure about Suzuki over here. But maybe it's too early to say. We'll see next time.

There are so many things that can produce strange sounds. Jezza, check this one!

[Jezza86]

as the issue being ongoing for a few weeks its unlikely to be ccat related lol.
if you have a old computer hard drive, pull it apart and get the magnets out of it
putthe magnets on the hub case near 18 and see if anything happens.
it could be as simple as a bad batch of magnets

No, I don't. I have taken my t-case skid off. It was too large and not practical at all. It was more like lawnmower than a skid. I grabbed all the fern and grass in my district. It's a desert now. Mike has suggested a compact transfer case skid that he has on his jimny. I think I'll buy that one.

[Jezza86]

Check your case is still bolted up tight and thats not making any noise

[jimny_timmy]

Or not over tight too

[Jezza86]

found my VSV1 is partially blocked/ dead. this was stopping me from getting warning lights when the vac hoses broke. i should have had a flashing light indicating the hubs wernt disengaging in 2wd. the auto hubs were causing my intermittent (and more constant over 60kph) grinding noises as when the engine was turned off what little vac was geting through released and the hubs moved inwards slightly, so a semi engaged position.

im now runing manual hubs, and spent the rest of the afternoon doing hectic lowrange skids.

this is the scary part but. after putting manual hubs on, my steering is lighter, and more responsive.

[zukenutter]

Why scary, if your auto hubs were engaged your steering would feel heavier.

[Jezza86]

Only 1 hub was engaging pulling the car to the right. Where oncoming cars are.

Good! Thanks for an information.
At least now you know what was wrong, I guess.
Hope to find what is causing my problems, but I would not like to switch to manual hubs.

The manual hubs are reliable and it is a very easy modification. The auto nubs will let you down when you need them one day. It has happened to nearly everyone. The change should not affect your new car warranty but you should check that with the dealer. You can leave the hubs locked and still switch between 2WD and 4WD when needed and then when back on the black top just get out and disengage the front hubs. It also has the advantage of being able to lubricate your front differential every now and then without engaging 4WD and you can also use low range 2WD.

These are the advantages and so far there are no disadvantages other than you need to get out of the car to engage them. Since you have to get out of the car to let the tyres down anyway it is no additional effort.

its made it a new car it handles so much better!

[dougies_tx5turbo]

well since we are talking about the vacuum hubs i should post this up. it helped me out when i was trying to figure out why my jimny wouldnt engage and disengage out of 4wd and hubs wouldnt work. so i'll post this up for other people, i should of done it sooner but i had to go through files to find it.

No grinding since June 26!
After all it seams the dealer was right, there was some manufacturing dirt.
Thank you for all your support.
