FD was leaking last fall, got it fixed and all was good.........for the next 2800 miles. FD leaking again. For those that understand these things, what should I be asking the shop when I take it back in for a warranty repair? What would cause the seals to go out again?

Thanks

I am on my second Crown and Roller bearing in under 18,000 and 2 years from the dealership. When I dropped it off for warranty repair I stressed what I learned here (hope the preload and shimming is correct and didn't contribute to the failure). When I picked it up I asked if the same was checked and verified and it was even written in their notes. While this doesn't ensure it is done correctly, it does ensure we are both noting the same concern and that things happen, in this case another premature failure. Parts fail, if it is only a seal leaking then maybe the o-ring wasn't positioned correctly or rolled enough that under use would cause a leakage, several variables. Give them the chance to make it right and keep going.

At least you can ride it there... ;)

Hey Brian, the half full perspective is that the warranty is still in effect!
and after they fix it again you should be good for another 2 years. Hope Steve checks real close for any metal chunks in the fluid when it's drained. That would prompt changing or re-building the FD. Assuming you are going to Portland MC that is.

John,

Two years would be better than 6 months and 2800 miles! Haha. Not PMC. Ever since they argued with me about a drain plug on my GS FD and told me they had never ordered a particular bolt/nut that BMW Says need to be replaced every time it's removed I seriously question anything they say. The seal was done at Cheshire. Will be talking to them today about another fix. Will bring up metal flakes, preload and shimming.

All replys so far are assuming it is your big seal at the wheel hub that is leaking.
Is that correct, or are you talking about the seal on the pinion shaft where oil would leak into the rubber boot at the driveshaft swing arm?

Oil leak at the wheel hub is a sometimes a sign of crownwheel bearing failure, but that is end stage bearing failure and you'd very likely notice other FD problems, but not everyone does.

Unusual for the seal to start leaking if the bearing is good and the surface of the hub where the seal rides is good. Corrosion or pitting on that surface would lead to seal leaking. Improper installation of the seal could also cause the seal to fail as early as you are reporting.

Yes, leaking into the boot for the second time. I have seen no oil on the rotor side if the FD. Last time since they were in there they replaced all seals ( I think )

Are you sure it is coming from the FD and not the transmission? That would suck, but it is something to verify.

Yup, from the final, having been through this 6 months ago............I know. I also checked the final and it was low on oil, due to it being in the boot.

The good bit of news is the shop apologized for the issue, told me to bring it to them tomorrow and they will get right on it in order to replace the seal and more importantly determine why it failed. So, so far I am happy.

The ring that holds that seal must also be "sealed" with a gasket compound. If not then it will leak past the threads.

Glad to hear it is not the tranny seal, and also that the shop will fix this for you.

$$$$$$ is right. I need to get a lift and just figure this shit out. The tech is a good guy, good shop, but dam, don't need to send his kids through medical school. Love the bike but this constant fixing shit on a bike with 30K miles on it is getting old. Hell, my truck is 10+ years old, 105K miles and the most its done is have the oil, brakes and tires done.

Need new front tire too since Avon piece of crap gave up the ghost after 2800 miles

Steering dampner is FUBAR

And tech is going to check some oil he saw in the bell housing. Thinks its blow back or splash from the tranny, but he is going to check. It had better not be the main. It was done before I bought the bike. If its gone out again, I am just going to freak. May be having a POS sale.

I talked to some of the folks here on the board and they talked me off the ledge, thanks John and Earnie. After seeking some advice, I called the shop and stopped the work. Picked up the bike up today along with the new tire. The tech said there was oil around the bell housing but they never got anything off of the bike other than plastic and rear sets (?) so not sure what he was talking about, but said there was oil around the bell housing, Wonder if he was talking about the outside, so thinkin he may have seen some oil from a recent oil change that I got sloppy with. I dont know. I plan on checking all the fluids and topping off as required. Put some dye in the final and then to watch what comes out later on. In the mean time, gonna ride, heck summer is sorta kind of finally here. Well for a day or so at least. Then at some point I will ask for some help from some guys here on the board to either do the work, with my help, or do a full blown tech day and dive into the thing and get what ever needs to be fixed fixed. As for the steering damper, got the bike home, rocked on the back wheel, slow turn of the front both ways, nothing. Quick turn both ways and I could feel the damper kick in, so I dont know what that was about either. Glad I didn't order one up!!

New front tire will go on and the warranty process with Avon will begin. See how that goes.

The steering damper is in good shape. Let us know how the tech session/repair goes.

I will, when we get around to that point, I will try to get some photos and some non-mechanical observations of the job.

Reading through your posts is like, well, either the definition of a bipolar BMW owner, or one with a "normal" love-hate relationship. :histerica

And yes he is bipolar, and having flashbacks to his childhood. lol :histerica
