Thoughts on welding/locking the differential in 02 lx?

 

only going in a straight line? sure.

have fun trying to take a turn.

 

That'll be a great way to destroy other parts of your car. The only safe way to provide better power output to the ground, will be an LSD.

 

Last LSD I found was $1400 for em2

 

That's typical pricing for name brand LSD's. If you don't mind doing some work when you get it, you can always do the budget-minded LSD and rebuild it when you get it. It'll need a rebuild when you get it, simply because they're not put together very well from the manufacturer (there's already tons of information out there regarding rebuilding them to make them perform).

Now that's a much better price! Are you talking disassemble and reassemble to make it perfect? Or did I misunderstand that?

 

Yes. They typically come with a horrible finish inside, and would easily lead to problems. Taking the time to knock off burrs, re-arrange the conical washers for proper pre-load, and cleaning up any casting leftovers would definitely yield a longer life for your transmission. Also, if you can, try and measure the run-out. In recent times, there haven't been issues, but the older ones they made were problematic.

 

That sounds like fun... Do they make a Different 5th gear I can toss in there to give better highway MPG while I've got it apart??

 

The 5th gear you have is already the longest you're going to get from a D17 manual transmission. If you change out your final drive to one from an HX transmission, you'll get better fuel economy... but your 1-4th gears will suffer on acceleration.

Maybe a trans shop will have something to fit? If its like s rwd. Trans it shouldn't be hard to do it, primary shaft and secondary with the gear?

 

Yeah, its a standard primary/secondary shaft layout. I do not know if the previous generation D-series transmission gears will work or not. I do not know the diameters of the p/s shafts to give any sort of solid information.

 

I'm sure if I asked, someone here would have it. Or google
