d/r 4wd, Yes

 

d/r AWD with locking center diff (RX), No

N/A 5 speed D/R 4WD, yes.

 

Turbocharged 5 speed D/R 4WD, no.

Yep, like the Doc says.

 

Turbo 3.70, N/A 3.90

Adding onto what the Dr. says...

 

The part time 4WD turbo D/R's were only offered on the 85-86 RX, and could be special ordered on 85-86 turbo cars. So, if it's got a 3-position D/R lever and it's 87 or newer, it's 3.9.

 

Easiest way to tell- count axle splines.

 

3.7 D/R of any type = 25 spline axle stubs.

 

3.9 D/R of any type = 23 spline stubs.

OK then, quick question for either Steve or the Doctor--the d/r was not available in Turbo wagons, to my understanding. True or false? Also--didn't the '85-6 cars with the turbo d/r, also have RX VINs even if they didn't have the RX badging?

D/R was available in turbo wagons. I have two of them sitting at the shop. one is a 86 and one is a 87. Both part time 4wd

Hmm. You really do learn something new every day. Either of them GL-10s?

One of them is a GL-10

one of them just says subaru where the GL-10 badge should be.
