The Scooby Posted February 5, 2004 Share Posted February 5, 2004 well i decided to climb under the scooby today to see what gears i do have, and if i do have an LSD, well it ends up i got 3.9's, so now i just have to go find a 3.9 LSD, much easier for me. i thought that 86's didn't 3.9's or was that with a LSD combo??

Meeky Moose Posted February 5, 2004 Share Posted February 5, 2004 my 88 gl wagon has a 3.9 open rear diff.. the only car that i know of that had a 39.lsd was the fulltime 4wd xt6 and even that was a special order option.. hunt around and you might get lucky.. otherwise the only way to get a 3.9 lsd is get a 3.7 lsd and do some modifying.. this summer i'll be putting a 3.9 lsd in my 88 wagon.. i just got lucky and know where one is at sitting on a shelf Quote Link to comment Share on other sites More sharing options...
calebz Posted February 5, 2004 Share Posted February 5, 2004 XT6 FT4WD 5 Speed was available with a 3.9 LSD Legacy (Turbo I think) Was available with a 3.9 VLSD 3.7 LSD can be changed to 3.9. I believe there is a how-to in the USRM Quote Link to comment Share on other sites More sharing options...
The Scooby Posted February 5, 2004 Author Share Posted February 5, 2004 you dont you just ahve to change the ring and pinon from the 3.9 stock to the other 3.7 settup? i know there is an atricle on here, but its not really that informative on how to swap the gears, unless i missed that part.

Dr. RX Posted February 5, 2004 Share Posted February 5, 2004 Look at my picture under my name, the is what the LSD tag looks like, a 3.900 LSD would look the same, but have 3.900 instead of 3.700 and a different part number. When you create a 3.900 LSD you keep the ring and pinion of the 3.900 and change the carrier (the part the ring gear bolts to). The picture the you show is of a stock 3.900 open diff available of every 4WD Suby that is not turbocharged. The rear diff on the Legacy turbo is a VLSD, and is really not a good diff to use if you plan to 4 wheel with your car. Quote Link to comment Share on other sites More sharing options...
The Scooby Posted February 5, 2004 Author Share Posted February 5, 2004 Dr. RX, this car isnt for off-roading, i finally decided on that, im going to get a EA81 or older gen 1 brat for that, this is a street car, that is gonna be a s-curve car. mainly autoXing. thanks for the heads up on what the tag looks like, now i know what it says. Thanks again, Shean Quote Link to comment Share on other sites More sharing options...
ezapar Posted February 5, 2004 Share Posted February 5, 2004 Aaron's Auto Wrecking usually has one of the VLSDs sitting around. But, you'll think a hundred bucks for a 3.7 lsd is cheap comparitively. Tom also sells them on ebay, know what they're worth. Quote Link to comment Share on other sites More sharing options...
Dr. RX Posted February 5, 2004 Share Posted February 5, 2004 Yea, Zap is right, if you can't afford $100 for a 3.700 LSD, then don't ever look for a VLSD. The prices that I have seen are between $200 and $400 for a VLSD. I think you best bet for autoXing is a LSD. Quote Link to comment Share on other sites More sharing options...
The Scooby Posted February 5, 2004 Author Share Posted February 5, 2004 well i can afford $100, but why pay that when people are gettin them from bone yards for $30 to $60 you know what i mean? so im just going to go and pull one my self, rather then deal with that other crap.
