The Truetrac is a helical gear limited slip differential and never “locks up”. I am positive its a limited slip. View the shame of a peg-leg burnout and wheelspin off the line, followed by the redemption of actually getting the driver's side tire to smoke in the water box! A spool is not a differential, and isn't considered to be limited slip, either. Military . In this case, both tires are maximized in terms of traction, but are just shy of their slipping point. Last week I drove my "new" '08 1500 in the rain for the first time. ? The Truetrac operates by transferring power from the spinning wheel to the wheel with the most traction. Disadvantages of a Limited Slip Differential 1) Lack of Full Power to Wheels This page was last modified on 7 January 2013, at 16:09. contestant, Trump reportedly considers forming his own party, Why some find the second gentleman role 'threatening', Pence's farewell message contains a glaring omission, Fox News fires key player in its election night coverage. Will spin both tires IF there is a lightly loaded rear end. My side is that LSDs are to make both wheels spin. So, checking whether a differential is limited slip or not isn't as simple as jacking up the rear of the car and turning the wheels, or seeing if both wheels spin when you hammer it. Step 1: The entire point about burnout is to make the tires spin or slip. http://en.wikipedia.org/wiki/Limited_slip_differen... Will Biden get rid of gasoline cars and make me buy a electric car? I need to know pretty soon. My friend says that LSds only make one wheel burnouts and posi-track its own type of differential and is made for every brand of car. I removed the cover tonight and took a look. isn't this opposite of what should be expected? Conversely, a LSD with a bent housing, worn clutches, or galled pinion gears and/or cross shaft may not allow both wheels to rotate in the same direction with the rear wheels off the ground. thanks rob-o Limited slip differential: lockup after tire spin? I'm really not sure why LS diffs are still offered. The result is reduced tread life, squealing of the tires even at slow speeds when turning, and a lot of stress on the rear end components. A Little Disclaimer. if you want both wheels to turn you have to change your diff carrier... the v6 up until 2004 had a one wheel peal diff... where as all gt models had limited slip rear ends. With that small engine and only being 2 wheel drive, yours probably has an open rear end. This is how my current tundra works. How do you think about the answers? Both tires always spin at the same speed, great for muscle cars, 1/4 mile racing and awesome traction. Lift the rear of ur car up, Spin one wheel..if the other wheel spins the same way then you have LSD. Under normal conditions if the rear wheels are lifted off the ground and one of these wheels is rotated, an open diff will allow the rear wheels rotate in opposite directions. they have alot of one wheel spin? LSD uses clutches to control slippage in rain or cornering. The Chevy Express van the Transit replaced had traction control on an open rear diff. In some isolated cases like the second generation Pontiac Trans Am, a 10-bolt 8.5" corporate LSD rearend was standard equipment, so they will have a LSD if it's original (except cars specifically ordered with an open rearend). LSD (Limited Slip Differential) has clutches, cones or gears in it that lock the axle mounted gears when the axle does not spin as fast as the center section housing of your differential or simply put the same speed as the other axle. A friend of mine got into an argument. Ive removed the cover from differential and know what a lsd looks like. The limited slip differential will allow some slipping between the two side gears, this allows both wheels to get equal traction even though one is spinning faster than the other.
