Hi,

 

We recently had both front LCAs replaced due to worn bushings (evident through premature outer edge tire wear).

 

About a week and a half later, we started noticing spots in the driveway and garage.

 

Today, I checked the Oil, and it was a little low, but still within spec, and the transmission fluid...

 

The trans fluid was not even showing up on the dipstick (yes, it was warm and running).

 

I added a quart with it still running, and it is still not showing up on the dipstick. I'm going to go get more now and keep trying until it is leveled up.

 

I took some pictures. I'm not a FWD person, so i don't know much about it, but it looks like the transmission is leaking near the CV boot? I'm not *sure* what the terminology for all these parts is, having only owned and worked on RWD vehicles for the past 20 years before this. Here are some pictures of the fluid soaked areas.

Any ideas of common problems like this? Could this be due to an error made during the replacement of the LCA? Maybe just an otherwise worn part that was pushed past its limits during the LCA replacement?

 

Any ideas on what to do before I take it to the shop would be much appreciated. I'm have no problem tearing it down with instructions. Finding the time is the hardest part...

 

Thanks in advance for any ideas or guidance on how to proceed.

Just topped it off to within the cross-hatches and it took 3 qts...

 

So, it's losing about 1/2 qt. per week. Is this stuff like oil where the cross-hatch area usually represents 1 qt (top to bottom)? Just trying to figure out how much I'm going to need to add how frequently until we get this fixed.

 

Thinking this is not good. Should I be looking for permanent damage to the transmission now?

I'd get her into a dealer or trans shop pretty quick.  I'm far from an expert but would guess you have a seal/gasket going bad.  Hopefully it can be repaired without tearing into the trans.

Leaks on the driver's side are known to happen more frequently on the 6F35 trans than the 6F50

6F50

 

But it does happen.  The halfshaft seal and/or axle will likely need to be replaced to fix it.  fairly simple job.  Could have been damaged during LCA replacement, but not sure how.  There is no need to touch the axle during LCA replacement.

Agree the LCA has nothing to do with the seal or axle.   Luck of the draw if you have a leak 1 out of three of my Edges had an axle seal leak but nothing outstanding.  More like a seep than a leak.

It turns out the half shaft had "slipped" a little bit, either during the LCA replacement or was loosened prior due to the vibration caused by having  extremely warped rotors.

 

The shop was great about it, though. They said "we don't know if we did it or not, but we'll fix it for free." They, reportedly, took the hub back apart, hit the axle with a hammer to get ti back into position and put the hub back together. Not a drop since.

 

I should mention that every day the leak got worse, eventually basically dumping a quart per day out on the ground.

 

Now I'm drops of thick grease on the ground - CV joint grease. Not a lot but just a couple drops. I guess I know what the *next* repair is going to be...

 

Thanks for your input , everyone. I'm glad that this shop stepped up and helped us out and took ownership of the repair. That doesn't seem like the typical experience to me, these days.

 

Thanks,

If it's not one thing ...  I believe axle replacement is the fix for the CV grease issue, unless it is just a clamp that is loose.

Great that the leak was a simple fix on the trans with the axle.  I will say I never had to move the axle to the point of this issue. I never removed the axle nut.  As far as hammering the axle not a good idea on that either.
