How To Check For Lsd

[SeiFeiRo]

Ive just purchased a 90 cefiro a few months back. It was a NA with RB20E engine previously but the owner converted it to RB20DET and he claims that the car has a viscous lsd. How can i confirm that it has a viscous lsd? If it doesnt have one in it, is it recommended for me to install a R32 axle?

do a burnout ..... if both wheels spin together as one its a lsd

lol. or you could jack the back of the car up. grab hold of one of your wheels and turn it. if the other wheel spins the same way its a lsd. if the other wheel doesn't turn or turn the opposite direction its an open center.

wouldnt u need to replace it with the s13 rear axle? i might be wrong

Depends whether the car is fitted with a 5*1 or 3*2 bolt pattern driveshafts.

S13s use the 3*2 bolt pattern, and R32s use the 5*1 bolt pattern. Just swap in an LSD from either one depending on what bolt pattern your driveshafts have.

Also, just to clarify, they don't have an axle as such because of the Independent rear suspension, it has the diff and 2 driveshafts (sometimes referred to as CV's, because they have CV joints in them).

Axle usually refers to cars that have a live axle (solid axle) such as KE/AE corollas for example.

Thanks for the help dan and qwk32. Will do that this weekend ^^

daisu,where can i find more info about the bolt patterns.

also it might just say lsd viscous on the side of the diff like mine does .........

Just have a quick look under the rear of the car, you'll see each rear wheel has a driveshaft (with CV joints) coming out of it.

The drive shafts then bolts onto the half-shafts that come out of the diff.

There are 2 bolt patterns for the halfshafts/driveshafts.

5 bolts evenly spaced, or 6 bolts arranged in 3 pairs.

S13 uses 3*2, and R32 uses 5 bolt. Most A31/C33 I've seen use 3*2 but have a look under the rear of the car and check.
