Before I ran the dutton Rally, I had my diff fully reset and shimmed up and it made a huge difference. Taking off in a straight line, the car goes straight and their is hardly any wheel spin, and cornering is smooth and presise and the grip is there. I think they torqued mine up to around 170nm where as before it was only 5 nm.

99% of the time it takes off harder and just goes nice and straight. It was not rainning when this happened but the road was moist from prior rain.So its probably my lack of experience with an lsd which had created that situation. I think that what happened was that under full throttle that the car launched straight and as the power was winding out just after takeoff the left tyre lost contact due to slight uneven road and sent the rear of the car out to the right. With the single spinner it would chirp and just keep going straight.
Driving around town the car definately feels more predictable and flatter to the road when I accelerate.It is doing its job . Just that incident prompted me to ask the question in line with safe responsible driving. I dont want to hit anyone because I am not used to lsd yet.

2grand damage, but thankfully i had insurance.

This also happen to my brother with his BA Fairmont, Xmas time when he left he gave it some peddle out front and it spun both, 2 weeks later only 1?
He did the same when it was a little wet out front and both started up again.

A sign of a single spinner about to kick the bucket is when both wheels spin.

And I must say - the N/A BA/BF Falcon diffs are pretty prone to failure. So I'd get it checked out if your diff is consistently spinning both wheels at the same rate.

He washed it one day took it out and gave it some stick, Spun both and kicked out hard. He has the car with 5 years cover so he wont care if it goes anytime soon they will replace it like the rotors steering. But maybe I'll tell him to call them and get it fixed earlier

.
I did something similar with mine not long ago, It was going single then jerked really hard left as the other side spun

I would suggest maybe tire pressure and the way your driving it maybe? Mums xr6 is no strip deamon but if you plant it, it kicks left, just have to respect the power. But in the mean time enjoy it while its still a new feeling

Im not sure if thats a good thing but it sound like a hell of a lot of fun!

Just drive the thing normally. I've never had a problem with an LSD. Unless I was asking for it.

Even at high speed I always make sure the front end end is "turning in" before I power on through corner...

You should use the throttle to dial out understeer when exiting a corner. If the front end is already turning in, more throttle will just make the front turn in more and the tail move further out.

I must be abnormal.. I can get into almost any car..FWD, RWD, AWD, LSD, SS, I6, V8, stock or worked and have absolutely NO ISSUES driving around on normal roads. On the track is different as you are pushing the limits but getting out of a FWD Kia Carnival and into my XR6 takes all of .00001 seconds adjustment time.

Tip for driving with an LSD on a low powered car (and yes, the AU I6's are not high performance beasts in any way) is just drive it normally. If its stepping out and causing greif you are on the throttle too hard (adjust driving style), your tyres are crap (replace tyres) or your suspension is rooted (adjust suspension setup). Simple as that.

i thought a locked single spinner was far worse and more dangerous than an LSD...

Agreed. Never use throttle to cure understeer when going into a corner however. I tried it once and ended up with more understeer and had to come to a complete stop a few inches from a gutter. So make sure the front is already turning in.

depends how much gas you give, mine always kicks out on a launch to better my position in traffic even if i don't want it to and i have an SS, but a manual in front of it

tyres and suspension will only give you grief on inclines ie roundabouts and thats mainly going at a certain speed that you'r car is forced to slide due to weight...this learning experience cost me 140bux....luckily no points doing about 25-30k's in a roundabout...

GreenMachine · 08-09-2006, 02:34 PM

Good god, Stav... Let's hope you never get any real power out of the old girl - AU Wagon shaped holes in the scenery all over Sydney!!!

Never experienced a problem with a LSD, tight or not... Only every had trouble with the locker diff on greasy roads in the rain, and even then, sensible use of the flat things in the footwell and the round thing poking out of the dash has seen me through...

The AU I6 has more than enough power to bring someone unstuck if they don't know how a LSD behaves, especially in the wet.

Hmmm Sounds like you've been driving mine

: But yeah, sounds about right. And definately watch it in the wet if TC is off.

What? You're trying to tell me a set of 8 year old 205s with a traction rating of T will be no different to set of brand spankers 255s with a traction rating of AAA?

A 120Y can get you in trouble in the wet.. but if you drive to the conditions its not an issue.

Booting it off the line in the wet, LSD or not, will cause wheelspin. A SS can be just as dangerous if not more so as the traction may cause one wheel to spin, then the other, then both, then none. With an LSD it is more predictable overall.

I don't know if a LSD is more predictable but it is the superior option for the type of cars that we have on this forum.Treating a LSD car like a SS car in the wet, whether it's of the line or accelerating out of a corner is a recipe for disaster.

no, you cant treat an LSD car like a single spinner.. if you are pushing it. Of course, if you are just driving normally and to the conditions you simply would never know the difference.

So what happens when you hit a patch of oil on the road?

same thing that happens in all cars.. you slide.

LSD or SS, both will react near on identical with an oil spill unless you choose to keep your foot into it.. in which case the whole "in control" theory goes out the window in both cases.
The LSD does not "instantly" lock both wheels into spinning. Lets take a couple examples:

oil spill hit by both rear wheels together..
LSD.. your spinning
SS.. your spinning
Consider it total loss of control of the rear.

oil spill hit by only rear wheel ..
LSD.. your spinning one wheel for a brief time. As the LSD Clutches lock up the spinning wheel will stop spinning (although still have basically no traction due to the oil film on it). It stops spinning because the unaffected wheel is not spinning (and wont as there is not enough drive to force it to spin) and the "nontractioned" wheel will "lock" to the non spinning wheel..and stop spinning
SS.. your spinning one wheel for a brief time.. then you either get off the throttle and it stops.. or it continues till the oil film is gone. Either way the unaffected wheel continues to drive the car (at a lesser rate) and you maintain forward movement.

Effectively.. exact same result.

LSD is not an "evil that must be learned" in normal driving conditions. Only when pushed (or taking off with one side in dirt and one side on tar) will the LSD show even the hint of difference. If it is kicking out under acceleration you are either driving out of the conditions acceptable to steady and controllable take off.. or you have a problem that would probably show itself under SS conditions as well.

you need tips on driving safely with an LSD? do u have a drivers licence?

There's my problem then i must not be steady or controlled

**Stav** · 09-09-2006, 07:58 PM

Well I have checked the air pressures and rectified them. Still something is wrong.The car in the rain is pulling to the left noticeably .I think it may well be my brakes dragging at the back. It has made very uneasy when driving it and I am driving very slow.The alignment pulls the car to the left but did not dothat with the single spinner? I am confused totally!! Could my rear leaf springs have something to do with this ?
