Is FWD front diff the same as AWD front diff
Just bought my first SVX. It's a 94 FWD with a bad front diff. I have a AWD trans from a 95 Legacy 2.2.
Are the front diffs interchangeable? Thanks Jeff |

the legacy has a different gearing ratio, but the transmission should fit, however I'm not sure if just the differential will fit

Yes, the front differentials are interchangable. You will replace the 3.70 gears in the FWD SVX trans with the 4.11's out of the legacy trans

Re: Is FWD front diff the same as AWD front diff
Can I just use the AWD trans and front diff and take off the tail shaft and put the tail shaft cover from the FWD trans on the AWD trans?

That would be great!!!
After I take the tail shaft housing off, what else has to come off the back off the AWD trans so that the FWD rear cover fits? Thanks Jeff |

Re: Is FWD front diff the same as AWD front diff
You will need to change the sun gears... a 35mm socket will loosen the pinion nut and the output shaft should pull right out. use a 2 bolt puller to get the sun gear off the end of the pinion shaft.
NOW... IMPORTANT. When removing the sun gears from the FWD trans, be sure to mark the gears where they intersect... Mark two teeth on the output shaft and one tooth on the pinion gear. This way when you re-assemble they go together with the same teeth interlocking. This is important because the gears are not only a matched set but they also should be kept as they were in the old trans... Hope all this helps. Tom |

I take it that the sun gears are only on the FWD cars and they will be replacing something that I have to pull off the AWD trans.
Thanks again Jeff |

Re: Is FWD front diff the same as AWD front diff
Tom, I'm need to jump in here. We've had a couple PM's. Tomorrow the entire tranny and diff will be dropped from the '92 Teal. Still haven't found a replacement tranny and diff with low enough mileage. My problem is a bad diff. You said labor time would be lower with an entire replacement, such as a 4.44. This is a first time effort so please excuse the noobie talk. Do you recommend trying one of the diff offers here knowing my lack of knowledge? This gear ratio thing is fast becomming confusing. There's a '96 Legacy available at the shop with a 2.2 engine which I assume is a 4.11. Would that require a rear diff change? The shop I'm at is a friend of 30 years but he specializes in Volvo/Mercedes/BWB and Porsche. He's facinated by the car but doesn't pretend to know the options open to me. Has done a great job with normal brake, axle, AC maintenace.
Gene PS: I gave Nicholas the "one wrench" instructions on removing the tranny and he said "duh". Crazy Serbs

My '92 with 79,500K and a rebuilt trans I'd like to keep stock but, the '92 Teal with 115,00K on a working tranny but bad diff I'm a little unsure of how to go. It can afford to sit until I get my ducks in a row and understand this conversion business. Shouldn't I try for something different. Your price is certainly good.

Got the transmission out and the diff off. Found about 4 teeth missing and the gear attached to the output shaft is mangled.
What causes this to happen? Tom, I pm'd you. Gene

Re: Is FWD front diff the same as AWD front diff
The transfer clutch drum probably sheered and the driver may have had some fun doing some burnouts Its not the first time it happened and I am sure it won't be the last... I returned your PM
