[01SERAD]

This is my first front wheel drive car (previous was '87 RX-7). Sometimes when accelerating somewhat hard I get some definate pull or grabbing in the steering wheel. Is this just your basic torque steer or could the limited slip also be grabbing a little ?

Thanks

That grabbing should be the LSD but LSD hits in in a coulpe of secs after you tear it up. I know what you mean, sometimes I think my car will spin out when I step on the gas on first gear.

it's natural for all front wheel drive cars to have that pull under a heavy throttle....it makes ya grab the steering wheel harder and grind your teeth and yell yessssssssss!!!!!!!!! HEHEHEHEHEHE

welcome to the wonderful world of torque steer.

for those of us who are ignorant and don't want to confess (I will for you), What is torque steer?

torque steer is basically the force of propulsion. in a RWD car, TS is what causes the *** end so swing out to the left or right when you spin the tires off the line. with FWD, since the steering and driving wheels are the same you get a pull to the left or right upon hard acceleration. <basically>

that's where the LSD (Limited Slip Differential) comes into play. EXAMPLE: take your car on a dirt road and stop. punch it and see the tire treads in the dirt. No LSD will leave one tire skid, whereas LSD equipped cars (Sentra) will leave 2. Limited slip comes into play when one drive wheel (usually the right one) slips or loses traction for X amount of time or distance. this engages the other (left in this case)drive wheel to have drive force applied. this usually creates additional traction and gives you the 2 tire spin in the dirt i mentioned. <basically>

don't be shy about questions...that's what this place is for.

so basically off the line, the lsd has no help at all? i thought it kept the wells from slipping no matter where you drop the clutch?

Actually, off the line is the major place where it helps. Think about it for a second, if one wheel is trying to pull the car while the other one is spinning helplessly, the car really won't get anywhere fast (hondas...) However, add a limited slip and after one wheel has spun for a predetermined amount, it locks itself up. Now you have both wheels pulling and nothing being wasted.

The only problem with a limited slip, is that when the torque applied back against the wheel is lost, a limited slip returns to its normal self as a differential. Thats what I found with my car, there is a lot of grabbing motion due to this load / unload situation.

When I considered getting the MX6/Ford Probe GT, I was told that they had equal length halfshafts which is supposed to reduce TS.

It sounds reasonable. I didn't get a chance to drive the Mazda/Ford hard so I don't know. Same w/ my testdrive for the B15.

Can anyone tell me if the B15 has equal length halfshafts since I don't have a B15?

FYI : Halfshafts are the driveshafts to the wheels in a [FWD?] car, they connect b/w the differential and the constant velocity [universal] joint.

Se w/PP has equal length halfshafts. Don't know about non PP.

 

[RadiumSE]

My VW Passat (as well as the Audi A4/A6) has both equal length half shafts and some sort of multi-link front suspension geometry and it has absolutely no torque steer. It's pretty complicated looking when I take off the front wheels but you can hardly tell that the car is front wheel drive when you are driving.

I also have felt the steering wheel grab, when making a turn with a hard acceleration. I always though it was the variable power steering ingaging.
