schottj1 Posted September 20, 2015 Share Posted September 20, 2015 (edited) I have a 2010 fusion with the 6f35 trans. I recently developed an oil leak and quickly diagnosed it as one of the CV shaft seals at the transmission. Looked like it was the drivers side so i ordered all the parts necessary to do the job. There is a terrific youtube video on replacing the driver side bushing/seal/shaft and i know i can do this by myself. The problem is as follows..... i noticed that there was also a couple drops of oil on the trans mount, which seemed odd to me if it was only the drivers side seal leaking. So, i sprayed a bunch of degreaser all around and cleaned the area up real nice, then took it out on a short drive to warm the fluids to accelerate the leak process. I drove it up on ramps and lucky me!!! Not just the drivers side, but also the passenger side seal leaks! It was a short, 20 minute test drive, and there was fluid just starting to develop around where each shaft goes into the transmission; but it hadn't started to drip and cover other areas yet, so i know it is two separate leaks. It is much slower on the passenger side, not that it really matters sense both need to be replaced. But i have been unable to find any how-to videos or write ups on doing the passenger side. Any info i can find seems to be concerning the drivers side axle shaft/seal. But the passenger side simply looks different. Ive attached photos of the driver side(1st) and passenger side (2nd) for those who are unfamiliar with what they look like. (pictures taken before the test drive so that is why it looks like there is no leaking) My question is, does anyone know if the passenger side uses different tools than the drivers side? I already have the special tools for the drivers side (bushing puller, bushing installer to set bushing at correct position, seal installer) but will those work on the passenger side as well? Because just visually looking at it, it appears different. I dont want to get the drivers side done, have the passenger cv shaft pulled out then discover uh-oh, i dont have the correct tools to complete the job. I would really like to do the job myself to save some money. I have contemplated just doing the drivers side, then take it to the dealer to do the passenger side to cut the bill in half, but that is a waste of expensive trans fluid (fill it up simply to drive it to the dealer for it to be drained out again). I would either like the dealer to tackle the whole job, or do it all myself. Preferably the latter. So has anyone done this before, especially the passenger side? Driver side i am comfortable with, but totally foreign to the passenger side. Or better yet, but a long-shot, does anyone know of a write up or a tutorial of someone changing their passenger side cv shaft and seal assembly? Thanks.

tsetse51 Posted September 20, 2015 Share Posted September 20, 2015 The difference is simply the length of the axle shafts. On the driver's side (shortest), the hub of the inner CV joint is very close to the transmission case, and the seal. On the passenger side, the inner CV joint is farther away from the case and seal, with a length of straight shaft in between. I don't know if both seals are of identical diameter, but the replacement process is exactly the same, after the axles have been removed. 0 Quote Link to comment Share on other sites More sharing options...
schottj1 Posted September 20, 2015 Author Share Posted September 20, 2015 (edited) Thanks. Yeah my only concern was to do with the bushing and seal itself. For instance if the seal or bushing sits deeper inside the case than on the drivers side, i would need a different specialized tool that will set it in at the proper depth. But assuming they are the same on both sides I might just go for it. Edited September 20, 2015 by schottj1 0 Quote Link to comment Share on other sites More sharing options...
mozz Posted September 21, 2015 Share Posted September 21, 2015 Thought the problem here was the axle itself being not smooth enough and wearing out the seal? 0 Quote Link to comment Share on other sites More sharing options...
schottj1 Posted September 21, 2015 Author Share Posted September 21, 2015 I think that is indeed the problem (for the drivers side), thats why im replacing the shaft itself as well as the bushing and seal. However, Ive just been informed for the passenger side it doesnt even use a seal. So how does it seal in the first place? Anyone know? Have no idea how to tackle it and cant find any info on it. So, going to be spending some money at the dealer tomorrow morning, unfortunatly. 0 Quote Link to comment Share on other sites More sharing options...
tsetse51 Posted October 2, 2015 Share Posted October 2, 2015 You've been wrongly informed. The seals are installed the same way on both right and left sides. The only difference is the length of the shaft extending into the transmission from the CV joint. 0 Quote Link to comment Share on other sites More sharing options...
Bob B. Posted October 3, 2015 Share Posted October 3, 2015 My experience with the same problem, and more. Each time I went for dealers service, I had taken the engine lower "windage tray" off to look for any transmission fluid leak. All done under warranty over a period of 8 months. 6F35 transmission. 1. Complaint. Fluid leaking from drivers side seal. Passenger side seal looks dry but a couple of drips from the casing. Repair. Drivers & passenger side seals replaced. (drivers side complete kit installed) 2. Complaint. Fluid leaking. Seal areas look dry. A couple of drips from casing. Repair. Drivers & passengers side seals replaced. 3, Complaint. Fluid leaking. Seal areas look dry. A couple of drips from casing. Repair. Replaced passenger side seal. Installed updated dip stick tube Assy. Still leaking (drips from casing) Re-sealed the casing halves, new torque converter seal, and drivers side seal. Looks obvious to me. The drivers side seal and the casing joint were leaking. (casing sealant D02) 0 Quote Link to comment Share on other sites More sharing options...
