Lsd

[USMC850T]

I hear tons of talk about 1 wheel peel around here, an I have to say that is not the case for my car.

When i drop the hammer and lay a patch, I don't spin just one wheel. Both tires lay solid rubber. Is there a way to tell if I had an LSD in the car? Any markings or ID plates on the diff itself?

I've just been wondering about it since I recently found my T5 wagon had an aftermarket rear sway on it (unbenownst to me (I actually bought one and went to install it when I made my discovery)). I'm quite curious to see if the previous owner did anything else to it.

Thanks in advance for any help,

Jeff

Put one wheel in the mud. If non LSD that wheel will spin.

With an LSD the wheel on solid ground will pull the car.

Looking at your location your car should be an automatic, which more or less answers the question already

It may not feel like just one wheel is peeling out, but it is. Get someone to take a video of it. If you do get any wheelspin on the other side, it'll be minimal. 95% of it will be on one side. Another way to tell is when you floor the car doing anywhere below 20 or so, the steering wheel will jerk to one side or another.

not all entirely correct. the 850 stock is a pretty well balanced car (which determines wheel spin more than anything in an open diff), given a specific driver's weight, it is very possible both tires could spin without the LSD. my 850 leaves even patches as it is, mostly stock. given more power and varying weight circumstances, i am sure this scenario could change.

there are many cars like this. one was the mazda miata, where the LSD option was largely ignored in the buying process due to the cars almost perfect balance and ability to spin both wheels without a LSD.

also:

That could be torque steer you are referring to. However, with torque steer the tires are not necessarily spinning, the car just pulls to the left or right and your steering wheel has a mind of its own during this time.

Yeah, which happens as a result of more power going to one wheel versus another due to axles that are uneven in length. Same thing that happens w/ a one wheel peel.

if you have an auto- no lsd.

A big anti-sway on the back with a t5-r anti sway on the front might be as good as it gets for these cars in terms of traction. when i put ipd sways on the car my traction situation became instantly laughable, i cannot nail it out of any corner without the inside wheel buring untill i let off the gas, same thing every corner or start from a turn. if i go more than 50% in any turn the inside wheel spins.

the traction from a straght start is much more even that any high powered open diff rear wheel drive car i have ever driven- due to the along the front axis drive train and equal length drive shafts, there is no drive train wind up of the chassis and rear wheel lift like in rear wheel drive cars with stock sways the traction was ok, but the car pushed in corners much more than i was comfortable with, so i am happy (actaully kinda dissapointed) with the trade off, but for me it is the right trade off. a big sway on the back might be the best setup for these pigs, if it does not push too much. mayby i'll try your setup someday. does yopur car push (understeer)?

my car pulls to the right when i floor it

definitely not LSD

put the car up in the air.

roll the passenger wheel forward

if

the driver wheel goes in the same way(forward), then it has an lsd

if

it rolls backwards (in the opposite direction of the passenger wheel), it's a open diff (stock)

Pics of your equal length drive shafts? How did you tackle that project?

"drive is transmitted to the front wheels by means of two equal length driveaxles" according to haynes

they sure looked like the same length to me when i looked at them....

When I had mine out of the car, one looked much longer than the other.

the passenger side is two piece- there is a mount to the subframe where the inside cv meets the anchored 1st section of the driveshaft. the cv to cv driveshaftafts are equal length. thats how my car is set up anyway.

there are pictures on ebay that show the set up if you type in "850 axles" i thought that equal length axles contributed to a better torque steer situation- but the load is too the chassis so mayby not.

hehehe

tis the truth!
