03 E320. Spent 3800 in suspension work and m, now weird ABS or buzz vibration sound?
Hey guys and gals. 03 E320 RWD 3.2 , 190k miles. Have a beautiful E320 and I just invested $3800 on the following. Inner and outer tie rods both sides. Lower ball joints both sides, new front struts, engine and tranny mounts, alignment and 4 all season Yokohama tires.
Now I have this issue that's wasn't there before. When I turn the wheel wide, mostly in reverse it sounds as if something electronic is turning on for about 3 seconds then off. It also makes a weird hollowing sound in reverse. Mechanic said suspension is fine as he doubled checked.
At first I thought compressor pump, but I dont have air suspension. Then I thought maybe ABS or wheel sensor or something? No ABS or ESP light on, so wtf? My mechanic is kinda stumped too. It also feels like I'm pulling a parachute now too. The car slightly vibrates on the road and doesnt glide like it used too. It doesn't seem like a tire balancing issue either. It doesn't pull on braking so doesn't seem like a stuck caliper. Maybe this is in my head cuz everything is now tight and new? The suspension is very nice and no rattles or thumps like with the old suspension. Also the ABS doesn't engage under normal braking so seems the ABS is ok, so I really don't know what is going on.
Any help would be appreciated

More details needed and when you hear the buzzing and where you hear it from, are you inside the vehicle when you hear it is a vehicle stationary with the engine running? Can you attach a video of the sound? I hope your mechanic isn’t going to milk you for more created sounds.
Honestly it feels like im driving with the parking brake on too. Do you know what wheel the parking brake is on?
No brake, ABS light on. Nothing. He better not tell me it's some ABS issue. Steering seems real heavy too but that may be the new tires. Car doesn't pull at all either so caliper doesn't seem frozen
Thanks !

Ha yeah, he better not try and charge me for anything else cuz this didnt exist before. When I first start out from park and go real slow it sounds like something energizes in the engine bayfor about 2 seconds then it goes off. I just backed up with the wheel turned to the left and there is a loud sound like a bear cub growl. It groans until I straight the wheel out. Definitely coming from the passenger right front.

BTW, Did you check the fluid level in your power steering?
try to post a clip of the sound you’re hearing.

parking brakes are on the rear wheels. You have an SBC braking system, it energizes for a few seconds to pump up the Reservoir, makes sort of a buzzing sound. My 2006 pumps up the reservoir when I open the car door, either side, when my vehicles been sitting for hours.

My mechanic literally checked everything.
This SBC thing thing you mentioned just pressurizes the brakes. It doesn't pulsate or engage anything? It still sounds like runs a few seconds whenever I first start the car. I Cant even drive it on the expressway because it doesn't feel stable. 😫

Suspension parts must be torqued down "under load". There's also specific tightening phases for some components prescribed as torque + additional degrees . Not saying your guy didn't follow procedure, but if not can and will produce altered handling characteristics and odd noises. Same for wheel bearing installs.

I'm going to somewhere else for another alignment first. I really feels it's out of alignment too.
The issue with my SBC could be completely unrelated to anything and just be coincidental. Buzzs every time I brake slowly. Fells as if I'm riding with brake on and pulling a parachute. I heard there is also some transmission reflash they have to do on 03 and 04s with the torque converter. What a nightmare. Hopefully this falls under that extended recall for the SBC! THANKS!

MB doc states: "Only tighten nuts and bolts of chassis cornponents when vehicle is in a ready to drive condition." meaning car resting on it's wheels.This can also be done with the wheel off and the suspension loaded at a point simulating the wheel being on. For torque values search this forum, they're around. This is why I perform as much of the work as I can myself as good help is hard to find, guys on this forum notwithstanding. Good luck!
