Central Diff Lock & Limited Slip Diffs Questions

[ch0k0y]

With 4wheel drives;
*The Central Differential is a mechanism to control variable speed between the front and rear wheels.
*The Limited Differential Slip is a mechanism to control variable speed between the Left and right wheels.

Please correct me if I am wrong and educate me further on this. I know you guys are more familiar with this. I may have more questions if these are right.

thanks.

Central Differential is located in your transfer case which controls front and rear propeller shafts power. While the Limited Slip Differential limits wheel spin from left and right wheels, mostly fitted on rear differentials.

Thanks for the quick reply.
So It is possible that in a part time 4wheel Drive(like Ford Everest), LSD may be present only in the Rear differentials.

Thanks for any enlightenment.

You will rarely find an LSD in front because manufacturers fear litigation when someone loses control because he did not know an LSD was in front (it can cause massive understeer when misused).

So when you see an "LSD" badge, 90% of the time it means a rear LSD.

...the picture clearer.

Thanks.

Not all Part time 4WD vehicles have the LSD options. One thing I know, Ford makes it a standard option to fit all their 4WD models locally.

[OTEP]

Unless it is explicitly stated as a front LSD, the term 'LSD' connotes a rear LSD only.

bihira lang ang LSD sa front.
magkakaroon ng tension sa CV joints.

Yung Gen 1 and Gen 2 Paj ba may Center Differential?

[kimpOy]

Gen 1 wala.
Gen 2 YES SuperSelect4WD

Drove my kumpare's Gen2, Texted Otep on how SS4WD works, just shift on the fly, instant all wheel drive.

pano mo physically malalaman kung may LSD yung sasakyan?

example eh checking it while all wheels are lifted? naririnig ko kasi dun sa mga personel nang servitek kapag minsan eh...pinapaikot nila yung rear wheels then masasabi na nila kung may lsd o wala yung sasakyan. kapag pinaikot nila yung isang wheel normally left side then nag-counter ikot yung kabila eh ibig sabihin ba non eh me lsd yon o wala? ganon kasi yung last kong experience sa servitek the last time na nagpa-align ako nung civic namin...yung nasa kabilang bay namin pinag-uusapan nila yung 4wd mechanism nung converted pajero... hindi lang minsan kong narinig yan...medyo hindi lang namin sasakyan yung tsini-check kaya hindi ako nakiki-uzi...hehehe

A center differential is only needed if the 4wd system is intended to work on paved roads (e.g. fulltime 4wd systems, SS4wd). It does not have any benefit off-road. It will even be detrimental to performance if there is a central differential that is unlockable.

An LSD equipped vehicle will have both tires spinning in one direction when both are lifted off the ground. An open differential will allow the wheels to spin in opposite directions.

so bale kimps yung strada naten walang center diffs?

[kimpOy]

wala jed,
part time 4WD tayo.
it's either 2H or 4H/4L

[ch0k0y]

inputs keep them coming...

I am really learning a lot. Thanks again.

Kimps,

Paano yung ibang Honda na may LSD? di ba front wheel drive yun?

[OTEP]

How many FWD cars have LSD? Bibihira. Usually sporting models lang. Almost lahat open diff.

A front diff itself is not really a cause for concern. It is the combination of four wheel drive and a front LSD that can turn nasty in the hands of an inexperienced operator.

frankdrebin,

iba ata yung calibration ng LSD for sports cars and LSD for off-roaders.

[Ungas]

LSD slip sensitivity settings are different for front end and rear diffs. There's more allowance for the slippage upfront than the rear sets. But basically same mechanical principles.
