Front Power train issue....
Anyway, on a 15o mile trip across the state in a snow storm last night the car started to make noise (thought it was tire wear at first) but they are new....this noise seemed to get worse as the trip came to a close (right front pass side) I stopped 40 miles from home, removed snow from the well and didn't seem to help....we got home, parked in the garage and thought I'll check in the morning. So did, all snow packed in the wells was melted, took it for a drive...seems as though there's also a ticking noise with it....as it moves faster it increased. This car was was absolutely silent earlier in the day as usual, so the tires are not the issue....my question is this...could it be cv joint? The differential, bearing or a combo of all? Transmission sounds and performs fine! Any body out there with this similar problem? Any thought? I'd really appreciate any thing!!! And what's MB warranty on power train?
Powertrain warranty is same as normal, 4/50k. So unless you have some sort of additional warranty, you have been out for 2 years already.
Just to eliminate simple things, it's not a nail or rock in the tire making clicking noise is it? That happened to me a few times. And clicking gets quicker as you drive faster, obviously.
Next thing I would make sure lug nuts are tight.
Today I had it in to the shop that I send my Volvo and Toyota to, they looked it over for two hours, pulled the right front tire (bearing is fine), then put it in gear and run it and used a stethoscope and listened to the differential and discovered the tick sound. He noticed the bearing on differential to drive shaft was bad immediately....and said, "it's time to get it to Mercedes, because this is gonna be expensive!" So.....how much is this gonna cost me? We've put 3500 miles on it since we bought it 3 months ago (current miles 41k)....now what?
If it's front diff then maybe it's possible to find a used or remanufactured unit.
Another way is to trade it in. Unfortunately, non of this will be cheap.
You should look for an indy that knows benzes. GLK and especially the 4matic system is pretty old and should be well known to good Mercedes mechanics.
Best of luck and let us know how it turns out.
