MY14 E63s Wagon face lift 93957 miles

I have a clunk on my front end. I originally had very bad squeeking and clunking, and found a broken lcross strut, the bushing failed. I replaced that and it cleared up most of my noise but I still have a clunk...

How to recreate:

Slow take off from standing stop. When the front suspension unloads, I get a slight clunk or knock. Very quiet.

If I'm turning slowly on a tight radius (think parking lot parking) clunk happens. Sounds like driver side. Not entirely sure.

When reversing out of my driveway, also get lots of clunk, but I also have to make a tight turn to back out, full lock on the wheel.

When standing with car on, turning wheel, it is apparent there. I hear the noise when going from full lock left hand down, to full lock right hand down. I get the sound JUST before center on wheel. Only apparent in that direction so far.


And from research what I can find as possible culprits;

Strut mounts
Swaybar and linkages
stearing rack



I do have a leaking diff in front, pretty confident it's the seal, on passenger side. I have a warranty (after market dealership warranty) but I'd rather fix it myself. Thoughts as far as what it could possibly be.

Regarding the front passenger diff leak… I thought I had the same issue. Turned out it was the passenger side engine mount leaking onto the diff.

This is what I'm seeing.

why don’t you want to use the warranty? One deductible to fix everything…?

ChewisHamilton

Yep. That’s exactly what mine looked like. I bought the new seal, got the ball joints removed but couldn’t get the axel shaft off. Took it in and had it done. $500 later figured out it wasn’t the seal.

Had them fill it with Royal purple just to confirm by color… it was the motor mount.

Let us know on the clunks/creaks. I’ve replaced both tie rods and the smaller linkage on the bottom that commonly fails. Helped but didn’t fix it all.

I'm fairly confident it is the driver side camber control arm bushing.
Extremely common failure, happened on mine before 10,000 miles. There are threads on here where people talk about it happening repeatedly.

One thing I find funny, when people post pictures of these cars on bring a trailer, I almost always noticed that the driver side bushing is shot. Lol
Anyway, I was able to fix mine just by pressing it back into place and tack welding it.
However, if I replace mine, I'll go aftermarket since the factory one always fails. I believe RockAuto sells them

I've had issues with the only MB dealer in town.

Krakenjack

did you by chance do your own rotors? I am feeling the clunk ONLY on the driver brake caliper and wheel assembly. Its strongest on the caliper. It doesn't replicate on the passenger side.

Krakenjack

so, after i did the 'cross strut' i went for an alignment at firestone and they weren't able to make camber work on one of the wheels -




do you have a link to a part number?

Krakenjack

took in for diagnostics -

****ing 165/issue to diagnose... so heres hoping they can point me in the right direction.

AMGfifty5

cheaper than the 250 I paid here in CA.

Krakenjack

yeah well they're charging me ... per issue... which is in its own right stupid as ****... 165 for the diff to give it a look over, and 165 for the clunk. Thats the down side to these high milage beauties... i may have gotten it for 1/3rd the MSRP but its still a $130,000 car when you take it in lol

I am going on my 4th driver side front lower control arm on my 2015 E63S with only 45k miles.... am buying this next one from FCP with their lifetime warranty so I never have to pay for this damn part again!

you can buy it from a MB Parts wholesaler for a few bucks cheaper but only get a 12 month warranty on it

I got a movtech one off rockauto. The bushing is huge compared to oem.

It's interesting that it shows on their site if entering the part number, but indicates it's not a valid replacement part when checking applicability for a 2014 E63. OEM part number on my 2014 shows as A2183302200 on EPC. A site that crosses the OE part you show, also does not show our cars on the list.

Krakenjack

See, I was able to find it on rockauto 3 weeks or so ago (check my post history) and I found it by filtering by my specific car. Now it's not there.... it fits perfectly. It's the exact same size in every dimension, except it's a smig thicker on the strut it's self and the bushing is significantly more robust.

Thanks for the link, will order a set just so I have them when it comes time to replace them.
