Manual Hubs

I personally would only lock them when planning to go offroad, ie lock them the morning you go on a days laning then unlock them after your last lane.

No point in accelerating wear on a component that wears quick enough anyway!

it used to be the case with old series landrovers that occasionally you had to lock up the hubs just to splash some oil about to keep everything lubed up including bearings and seals..

I guess regardless of manual or vacuum hubs we still have to do 'lock up' occasionally for the same reason?

I just used to unlock the drivers side hub less drag also should stop the prop from spinning giving vibration may be

I do so few miles it is not an issue. In fact, I did the same on my SJ as it, like this, stood around so much it needed a bit of action.

Yea I heard the same Yellostreak , keeps the bearings lubed.

HI, I just saw your post and I had to as what was the reason you replaced vacuum hubs with manuals? Something wrong with vacuum, or?
Forgive me, but I think I have some vacuum hubs issue.
I had hyundai galloper (previous to jimny) about 8 years and that car has never failed. But I wanted to sell it while I can still get some money because I admired jimny. So, November 2013 I bought a new jimny (2013).
But 3 weeks after a first drive I noticed some problems. While driving, suddenly a grinding noise starts and it seams like my jimny is about to fall apart. Previous to this I was off road (using 4x4 just for a short part of road) and just returned on the city road (2x4), driving about 50 km/h. Next time this happened car was about 2 months old. On the highway, at speed of 120 km/h. Ever since this happens once or twice a month. Mysterious terrible grinding noise, can't even say for sure where it comes from. It is so loud that I could not judge. It seamed it was somewhere in the area of front wheels. Sometimes it seams like metal grinding, other time it seamed to me it was rubber-grinding noise. I drove about 2 miles before it mysteriously stops. Noise disappeared by itself (first time). Next time I stopped an engine. The moment I started an engine again, the noise was gone. Third time I stopped the car, with an engine running, than switched 4x4 for a short while and the noxt moment grinding disappeared.
I was told on this forum that the cause of grinding are locking hubs and I am about to make my second trip to the dealer (first time he said everything is fine). But, can't help myself, I am not happy with jimny anymore. Besides this grinding noise, I also hear some bumps on the rear side when changing speeds. But there other things, too, and since I have a brand new car and already with 5 or 6 different (mechanical) knockings and grindings, I became paranoid. It warries me that jimny is nothing of what I've seen on youtube and forums - nothing of what I hoped it would be. I have lots of doubts. I thought this was a seriuos offroader, solid and reliable. And now, suddenly I am afraid to take it offroad thinking something is about to fail or fall off.
This is why I'd like to hear from others if they have had some issues, how about jimny offroad etc.
Thanks.
