I've got a The Driveshaft Shop carbon fiber shaft on the way and that is a great idea.

I've not looked at it closely, but typically it is just a press on...so use a screw driver to carefully lever it off and tap the new one on.

I've got 140,000 so automatic to do.

 

I've pulled the driveshaft out of my Forester repeatedly and never replaced it, and it has 113k miles.

Can't hurt, but far from mandatory in my opinion. A typical shaft seal puller should be able to get it out.

 

I would agree not mandatory.

I prefer to not go back and do the same thing twice if I can help it...for 7 bucks-seems like good idea.

 

This is something I've been contemplating after reading many positive reviews. Most reviews I've read are from people replacing the ds because of oem failure. Your car is pretty new, any reason to replace so soon? I only ask because i'm trying to justify spending 1k to replace a ds that is still good. Also, what brand did you go with? I've been looking at drive shaft shop.

 

Right on... might as well swap the seal in since I have it, and it seems easy. I HATE having to repeat work (yay stripped crossmember bolt ), so better to prevent a leaky seal now.



My quest this year was to improve driveline feel and response, and the lighter weight CF driveshaft is the last piece of the puzzle. The stock unit weighs ~30lbs, compared to the paltry ~12lbs of a CF shaft from DriveShaftShop :tup: Benefits are: less rotational mass = better pickup, more power going to wheels, less lurching/bucking. There's some reviews out there that give a good overview of the bene's. I'll add my own after tomorrow

 

My shaft(s) is original...very pricey upgrade that I've delayed until I feel the factory two piece is aged sufficiently.

I could think of many other things before I swapped to this on a newer car.

I recall spending $550 on an aluminum shaft for a domestic vehicle years ago...and folks thought I was crazy...now I just dropped nearly twice as much! Admittedly, the $$ aluminum shaft has never broke at the drags...that is worth considerable.

 

I replaced the seal last night while installing the new CF Driveshaft. Was fairly easy, just used the screwdriver+pry method, and it came out with very little drama. Used some trans fluid to lube the new seal up, and it went in without a problem. $8 for piece of mind :tup:

 

I just ordered myself a CF DDS driveshaft! For those of you that have done the seal replacement, was it on the GR model? If so, I'm hoping someone can help me out with the part number. I'm seeing two: 806732200, 806735210 ?
