Good idea of questioning it, definitely need a second opinion at this point. I believe even motor mounts are very premature too if true same goes with transmission mounts. If vibration at speed could be bent wheels as well.

If it is a vehicle traded into that audi dealership and listed for sale, they should had got things fixed before listing it and not at your expense? Unless they are selling it as is.

I am only skeptical because axels going bad on this car is rare to none, the only common issue are leaking shocks. I don't want you to be ripped off by the stealership.

Recommend getting a PPI.
I beg to differ. Front axle CV joints going out on W205 cars is very normal. "Clicking" CV joints are almost always the outer side. There are repair kits from MB to just replace the outside CV unit, leaving the shaft and inner CV in place.

Aftermarket axle assemblies are junk. Only a solution for someone who want the problem to "go away" before they sell the car.

Strange, not my experience but your mileage may vary for sure. It doesn't help that the rims crack so easily on our cars, that might contribute to it, I went with aftermarket wheels long time ago, my axles still in good shape.

That said, do you mind linking the part number of the repair kit and/or the WIS guide to perform the repair? For future reference? Thank you.

They want 16,991 with 80k miles. Consistent oil changes and everything looked good.
1.They are detailing it and addressing scratch on bumper. cabin filter, oil change, replace front axles.
2. Center console chrome peeling, driver switch worn, back pocket on seats broken
they want me to pay for.

He's going to verify brand of front axels. Don't know yet. Beyond this it's as is.

Lot of torque to handle properly and after market inferior from what I've read. I always thought CV joints would would last for well over 100K miles.

Thanks for the input.

They decided to put XL parts on for axels. I've never heard of this brand. LOL.
Sounds like their in house brand label.

I gave them the repair kit numbers and they blew it off.
They are definitely doing bare min to sell it.

Well if everything else is in good condition and you like the car then you could choose the go ahead what about the vibration you mentioned?

Once the sales guy confirmed they went with the aftermarket axel garbage, he stopped providing info.
They were not going to touch up the bumper scratch unless I bought the car.
They never did pinpoint the vibration conclusively. It seems like a lot of service dept. have declined post-pandemic.

The thermostat will break anytime between 80-90k. Struts at 80K probably have another 10K life. $1,000 for the struts, just parts.
Engine mounts with labor probably near 1K. The interior will need $600 in parts due to wear/broken.
They would not lower it one penny. Man these guys are cheap! They call it a value vehicle.
Not worth taking on for 17K plus tax, DMV.

I found another car so will go with that one if FaceTime pans out.
This market is crazy. Tough to find a car with good value that does not need a lot of work.

​​​​​​Part labeled #50 in the diagram above:

Left side unit is MB part # 2053309910

https://mbparts.mbusa.com/oem-parts/...int-2053309910

The boot kit is separate, you'll also need a new axle nut since it's TTY.

I don't have the factory manual. You just disassemble the front brakes and suspension enough to remove the axle, put the shaft in a vice, remove the old boot, drive the CV unit off the shaft with a hammer and a brass punch, then do it all in reverse to put it back in.

It should. I will see the car next Friday. It has 40K miles. I presume once it hits 60K miles
this issue will present itself.

We are still in the R&D phase with these mounts. There are many factors we have to consider with this design and we are working to ensure we are considering all variables. Unfortunately testing takes more time than anybody really wants it to, us included! I wish we had a better update at this time, but we have not forgotten about these engine mounts.
