I want to know If I have an locking diff or a non-locking diff. I have this

tranny code here: RE4FO4A. I am sure I haev an non-locking but I want to

confirm beofre I do anything else. Thanks

 

Open(non-locking) differential....The "A" is key..

 

so i was right thanks dude.

 

What letter designates for Locking?

 

"V" for "VLSD"

 

Indeed.

A == Open
V == VLSD
H == HLSD

 

What the in the "Sam Hill" is a HLSD?? Never heard or seen that trans in this web site...

 

HLSD == Helical Limited Slip Differential.

Basically it uses gears to assure torque transfer instead of a viscous coupling, such as found in the 4th and 5th gen VLSD 5MT (RS5F50V).

There was never an HLSD trans available for the A32, only A33B-A34 6MT, the RS6F51H.

Here's what the diff looks like, notice all of the extra worm gears along the top and bottom:

pmohr,

Whoever you work for, they are NOT paying you enough, at least not for the knowledge that you have....wow, I'm truly impressed.

 

Not working right now, so definitely not making enough, heh.

 

quite so. i think he was a nissan engineer in a past life.

 

I sure hope I wasn't the one who designed the placement of the KS, or I'll have to kick my own ***.

 

Actually, the ks is mounted in the best place to listen for knock, the failure imo is in the k/s design, the engineers/manufacturer of the k/s failed in making the part out of substandard plastic. I've seen several(including my own) k/s on the ve30de engine where the k/s was literally melted down into a indistinguishable heap of plastic from heat damage.

BTW, the VE30DE k/s is the same part# as the 4th gen VQ k/s.. and is mounted in the same place..

 

Yep, seen a few of those myself, nice and melted.

Well it's not so much the KS placement I was complaining about, just the procedure to get to it.

Then again, if I designed the car, everything would be held in place with latches and V-bands, heh.

 

LOLOLOLOL, sorry just couldn't help myself, thought everyone would appreciate the "laughture"

 

Sure is a lot of nut-swinging around hurr...

 

In the stickies with details
