I googled for this, but I may be handicapped. I cannot find anything about HLSD. How do I find out if I have LSD? I'm sure this has been discssed before, but yahoo searh of forums does not turn anything up, and browsing through 20 pages of posts does not show anything for this either.

1. Open your hood, look on the top right side of the engine bay and you'll see a plate with various numbers, with the VIN one of the numbers... look down to find the numbers to find the transaxle code.

2. If its RS6F51A ya have open differential. If its RS6F51H then ya have HLSD.

 

Here is something I found about Lance EVO, but I'm sure it applies to all of us with VLSD or HLSD.

The front differential's helical design provides it with smooth operation and superior responsiveness. Small in both size and weight, the helical unit does not require special oil or additional maintenance.

Helical-type limited-slip differentials offer several advantages over the clutch-type or viscous LSDs. Viscous limited-slip units tend to wear out after extended use, as their oil is heated and reheated until it degrades, rendering the unit ineffective. Clutch-type differentials provide good off-the-line traction, but the 50/50 stability that's beneficial in a straight line is not so desirable when a vehicle is turning. The helical-type limited slip provides better durability and performance when it's needed most: while turning. Unlike an open differential, which shifts power to the wheel with less grip, the helical LSD constantly shifts the bias toward the wheel that has more traction.

Under straight-line acceleration, power remains evenly split between the front wheels. While cornering (e.g. accelerating out of a turn), the helical LSD directs power away from the inside wheel and toward the outside wheel, allowing the driver to begin accelerating earlier and exit the turn at a higher speed, without losing traction in the process.

P.S. Thanks for the above reply Puppetmaster.

 

Do youm have drilled metal pedals? (sorry I didn't read the link if it's already there)...

 

It doesn't do much for straight line accel just cornering and now melting your inside tire.

 

If ya have time to type "(sorry I didn't read the link if it's already there)" then ya have time to read the thread and do a search for more threads on this.

Yeah, I bought the car used, and it has AE door sill, and drilled pedals with rubber padding glued/inserted to the bottom of them. My chassis number on the inside of the engine compartment says RS6F51H, think this means its got helical LSD. However, when I am in 2nd gear, really hitting the gas, past 4k RPM the car starts pulling to one side or the other a little bit. I was under the impression that HLSD or any LSD was supposed to prevent this from happening. Also, does HLSD or any LSD help in wet weather on a car w/o traction control?

 

I checked underneath my hood and it read 'RS6F51A'. So what does this mean then? Which do i have, if it ends with 'A'. Btw, its a canadian maxima.

 

Way to learn how to read DUKEE.

 

HAHA, damn. Sorry, i meant 'V'. It reads RS6F51V!!!

 

The yes .. VLSD because there were no HLSD's for your year.

 

Are ya sure you're not thinking of torque steer? I can dump my clutch in first at 4000 and even though it hops for a bit, it doesn't pull in either direction... same thing with 2nd gear all the way to redline (trust me, I've tried it). Straight as an arrow.

And yeah, it does help a lot then accelerating through corners in slippery conditions... you do notice it.

 

Yeah, sorry I didn't clarify the years on that... what I posted was only for 02s and 03s.

 

mmmm.... i think i am thinking about tq steer.

 

Do VIN search or jack up front wheels and turn them (put in "N"). If they are rotating in the same direction you have LSD.

 

Actually, I don't need to do a search on this, I know the pedals indicate it has HLSD unless it was a for show only modified, so I was simply asking the ? and didn't need to search for info!
oh yeh, I can type real fast!
