Phizinza Posted May 20, 2006 Share Posted May 20, 2006 I need to know what type of rear diff I would find in a 87 RX Auto. I want a 3.7 LSD, but I am unsure on what ratio auto RX's have... Anyone know? Cheers, Phiz Quote Link to comment Share on other sites More sharing options...
calebz Posted May 20, 2006 Share Posted May 20, 2006 We didn't have any auto RXs here except for the latter half of the 89 model year. Not sure if that info would be applicable to you. Quote Link to comment Share on other sites More sharing options...
JWX Posted May 20, 2006 Share Posted May 20, 2006 if its the same, its not a diff so much has a viscous coupling. I think? Quote Link to comment Share on other sites More sharing options...
mikeshoup Posted May 20, 2006 Share Posted May 20, 2006 Easiest way to do it, is to check the label on the rear diff. It will tell you what gear ratio it is, and if its an LSD or not. Quote Link to comment Share on other sites More sharing options...

I would check it, but for the fact the car is 840KM away from me and the guy could only read the word "oil" on the sticker... Oh, and I made a mistake.. it's a 85 Auto RX...

SOOBOUTLAW Posted May 22, 2006 Share Posted May 22, 2006 I've always seen 3.7:1 in the automatics. Quote Link to comment Share on other sites More sharing options...
AWDGLF5 Posted May 22, 2006 Share Posted May 22, 2006 L series turbo automatics that are Australian delivered are most likely quite different to the US specs. Most came with an open rear diff, although I have seen a few with clutch pack LSD's. Quote Link to comment Share on other sites More sharing options...
Phizinza Posted May 23, 2006 Author Share Posted May 23, 2006 Hmm... This is making it hard. It is a RX sedan, and from what I can see that is the only car you get 3.7 LSD's in Australia from. Although you say the automatics are most likely open... ahh... Maybe I'll have to wait for another donor car before I buy, one I can make sure it has all the parts I need. Either that or go to the wrecker and spend $$$$ on the diff and brakes. :-\ Quote Link to comment Share on other sites More sharing options...
