Suzuki 4x4 Jimny underside - possible issue with transfer case?

Metallic tapping/tinging noise coming from driveline when car's rear is loaded (either heavy rear passengers or with toolboxes. Tapping noise becomes a grind coming off speed bumps. See 2:02, 2:33, 3:25.
Edit2: 2017-09-05: Replaced diff centre, with the noise and vibration still happening. Looking at a possible failed bearing in the transfer case.
Edit 2017-08-20: Ended up being the rear diff pinion bearing on the way out. The issue got worse and the bearing complete failed, ending up in a deep vibration from the pinion and ring gear operating at a off angle, and a bearing howl, both under acceleration only.
If you get this tapping, metal scraping or grinding noise over bumps, have the diff repaired before the pinion crown gear and ring gear wear are damaged, or start looking for a replacement rear centre.
Also fix your driveshaft cv and radius arm bushings.

Hi, sorry, what's the solution for this problem? This noise is terrible when the jimny is loaded, thanks for your help

Rebuild the transfer case people. Seals and the bearings are worn. Amazon has a kit for under a hundred bucks. Also the output from the rear differential is worn out on this samurai, as a result of driving with the transfer case bearings being worn out 🫣

Mines (2009 done only 67,000ks)groaned on fast first gear takeoffs for the 12000k's i have had it(same sound as around 3.05 minutes in), but today i heard a quiet bang, while coasting downhill in 3rd gear, and from then on she makes a loud scraping noise(bystanders turn and look) similar sound to a stone in a brake, or a bearing spinning in its housing, which comes and goes, mostly above 30kph, but mostly goes away when very slow. So i had to slowly limp home 60+km's(including hills)trying to avoid worse damage, although twice i got to 60 for a little while on the flat before it started again. Applying brakes lightly makes no difference to noise(and they work fine and smoothly), nor does putting her in neutral(but reduces as speed drops), but as its a pushbutton model, unable to put transfer in neutral to check if from gearbox. Notice a loud- ish clicking noise at each rear wheel when spinning them, but bearings feel fine and wheels spin smoothly(unsure if sound is usual for them or not- (edit, many say yes) possibly just being transmitted thru housing from inside diff - spider/sun gears? or some think abs related). Ran her up to 160kph on axle stands, and can not replicate noise with no load on her, nor by applying brakes to stalling point while still on the gas, all gears still working fine and smoothly. 4wd still seems to operate ok too. Drained transfer oil, looks ok. Drained gearbox oil, seemed a bit too bronze/shiny looking....., but no debris on magnet and not at all black. Drained rear diff, magnet had a thick very black gooey mess attached, and oil was slightly black, but no obvious large metal particles in it. (all oils were strained and checked, and only had some very small metallic fragments visible to the eye) All oils were last changed with correct ones 12000k's ago(by me), and never been used in water by me, but i do use redline revs in 2nd an 3rd gears, quite a lot. ps, did notice that same groan in deep sand, in first and second, the one time i was on a beach (sounds like an overloaded bearing to me). So thinking a diff issue, but do wonder if the first gear groan means gearbox output bearing. Unsure what to look at next, so thinking i will do like poster, and record a video while driving. Wondering if a bearing is spinning in its housing when hot..... Haha, just noticed age of thread, oh well.

That looks like the bushings worn on the radius bar letting the rear axle slightly rotate under rapid acceleration and over bumps IMO

Could you do the same video for front drive shaft? A comparison between 2H and 4H. Thank you

Bearings in the in box, need a rebuild.

Thinking along those lines for mine, but perhaps my diff too? (see my post)

hi does it get under pressure to drive while turning with clicking sounds?

@cgrecommended 4 жыл бұрын

Cars is long gone, no clicking noises but under load it had crazy vibrations. Was either transfer case output shaft/bearing or bent diff housing. I ended up replacing the diff and rear driveshaft to no avail. The problem went away when I removed the rear driveshaft and drove it with the front wheels.

Sounds like an old Land Rover Series.

Was just thinking mine was sounding a bit like one,(whining sound) just before events mentioned above happened. Was warned after buying her by a dismantler, that boxes were weak in them, and often die. (seen rear output bearing failures, destroying internals on a forum, and just now a repair post with full rebuild info that said -If you get horrible grinding sounds when cruising in 3rd and/or 4th gear, that's a sure sign that you most probably have this gearbox bearing problem, -talking about layshaft bearing), with mine seeming worst in 3rd , and it happened in 3rd, thinking could be it.
