LSD

[simonwedge]

When the car was jacked up the other day I noticed that, if I turn one of the back wheels by hand, the other wheel turns in the same direction - indicating that it has a LSD fitted.

The car is an '89 350i and therefore I don't think was fitted with an LSD as standard. Were they offered as an option or has it been fitted since?

Think all the later 350's got them along with the transfer to A frame rear ends...?

My 86 350 had a powrlok diff

I thought it was always an option on the 350i but standard on a 390SE. The rear cover plate should have a small metal plate retained by one of the bolts that reads 'PL' if it's a PowrLok; another plate should tell you the ratio (commonly 3.54:1, my car has a further option of the 3.31:1).

I've now read in the Bible that the Powrlock diff was an option on earlier 350's but was fitted as standard to all later V8's, the changeover being about when the A-frame rear suspension was introduced.

I'm sure my 88 350i also has an LSD .
