Consider Qualis or SUMO ehich has got RWD & yes they can be driven safely above 100+ KMPH. But IMO, what ruffyrider meant to say is for a vehicle with T'case, even in 2H mode, the front drive shaft rotates. (Only free wheeling hubs are disengaged). So driving faster than 100 KMPH may put stress on T'case.

I think this may be the case with simple 2 speed T'cases. Well, this is what I can guess.

My bad. Sorry for that. just trying to exlpain it in simple words. Actually now-a-days many offroaders have 4H drive ratio such that more power is given to rear wheels.

I am no Jeep guru, I have owned Jeep only for 4 months.

But I do have some little understanding of 4x4 vehicles since I own couple of them. What you said kinda went against what I knew, that's all.

Hey sir, looks like you will ask the mods for a "falling at somebody's feet" emoticon. Your friend misinformed you - 4x4 is not an easy world to understand and therefore, one must be extremely careful in what one posts.

Default 4x4 vs AWD

Hi, I have almost zero knowledge about 4x4 and jeeps in general. But the other day, I had a chance to drive a Subaru AWD sedan.
So I was just wondering if 4x4 in jeeps is same/similar to AWD in sedans like Subaru and Audi?

If it is, then theoretically, can a beefed up (large rims, large tires, increased GC etc) AWD sedan perform similar to a Jeep in OTR?

1.) You can look around Google and this site to find the differences and similarities. There is plenty of info on it. I won't rehash it here.

2.) "Theoretically" yes, practically no. It's a cost thing. It is an expensive proposition to diddle with the suspension of a Suburu or an Audi to get the GC and tyres you need under you.

I wish Suburu was in India. They make good quality simple vehicles that are stone-reliable. You would think it would be a natural match, India-Suburu.

If you want to read a funny/informative/heated discussion on some of this read http://www.team-bhp.com/forum/4x4-of...odern-4wd.html

Isn't the GM Forester a Subaru variant with AWD?

Sorry but could't stop but mention the tractors drivetrain.

Like a Tractor has Kachua (Turtle) and Kahargosh (Hare) gears. Mostly in 2WD tractors.

Turtle being Low ratio and the Hare being High ratio. Similarly in 4WD jeeps 4H high ratio and 4L low ratio.

Regards,

Randeep

Nice write up, I have never driven a 4WD jeep/gypsy, never got a chance actually, these things are not available in showrooms or for TD :( for a very brief moment I had driven the Gurkha but couldnt explore a lot of its capabilities.

Default Basic 4X4 Terms

Jeep Gurus,
Being new to the 4x4 off-roading sport I have come across many terms which are a bit difficult to visualize without proper explanation and /or some guidance in form of pictures/ videos.
I would like to know what is:
1. Pitch
2. Roll-over angle (does it have same values as the approach and departure angles)
3. Flex vs Articulation (Are they the same terms? i.e can they be used interchangeably?)
4. CV joint
5. ECM
6. types of differentials
7. effect of lifts on steering and suspension
This is what I could think of now.
Please help me understand these terms. Also if anybody has something more to offer please add here.
