2014 E-350 4MATIC torque specs

The only way to upgrade the firmware is you have an online account of the MB Star. Someone might offer the account rental. Or upgrade it at a dealer.

Due to your video showed the moving part of the drive shaft, I considered the snap ring or the retaining ring have damaged. If my guess id correct, to replace the rings is away cheaper than the entire shaft.

Did you feel any abnormal while shifting?

@Senior Leigh | 老李

yes especially when cold

I think I need software update do my values look normal also should I change that cv axle ?????

@gregory.baldwin.jr If you can upgrade the firmware of the AT, do it, or tried to replace the ATF might improve the rough shift.

For the CV axle, check the snap ring and the retaining ring before you replace the entire axle.

@gregory.baldwin.jr I think that's abnormal.

@Senior Leigh | 老李

should I change the axle ????? It has play

@gregory.baldwin.jr If that's play, you'd consider replace it.

Is the clunk when you slightly turn the steer wheel left and right?

@Senior Leigh | 老李

no clunk when turning wheel its when I push the wheel in and out like on my video the car feels wobbly and rough at times it’s definitely something wrong with the front left wheel??? could it be strut ?

Steering does shake and vibrate at low speeds

Senior Leigh I took everything apart and made sure everything was tight when I put it back together it is still making that noise I think it’s the bearing

@gregory.baldwin.jr The driveshaft is normal. If the bearing is worn you would hear the squeaking while driving. So after you put them back, if the vibration is still, you might focus on the steering system, check from the tie rod.

@Senior Leigh | 老李

im getting a low speed wobble. the tie rod is tight the inner tie rod moves around easily but no in and out play. If I put my hand ✋ on top of tire and rock it I hear the same noise it only happens when the car is on the ground. when the car is jacked up the wheel is tight. that’s why I think it’s the bearing sounds like a knock noise. Also Merry Christmas 🎄

@Senior Leigh | 老李 so when driving should I accelerate slow after the reset? Should I keep the vehicle in comfort mode ?

@Senior Leigh | 老李 this is my software version on my transmission is my software old do I need update ?

@gregory.baldwin.jr after reset the logic of shifting, just drive normally. After a week driving the shifting would be smooth again. Your Star version is pretty new, no necessary to upgrade, just keep the data status newer than your car is ok.

The max load pressure on the gas door is the same as the front door frame.

That's weird, normally the tire pressure guide should be on the inside of the gas door. In my experience, the 4Matic tire pressure is the same as the 4 tires. For a two-wheel-drive car, the tire pressure on the driving wheels will be higher. Since your E350 is 4Matic, I suggest you set the tire pressure as the same as front and rear. From 33 psi to 41 psi are safe for your car. You might balance the comfort and fuel economy to determine the tire pressure. I set my E350 tire pressure as 35f and 36r.

@Senior Leigh | 老李

ok I need a load tester I see can I just go to a part store and let them test my battery with their machine

@Senior Leigh | 老李

can a weak battery cause my transmission to shift rough? Never knew that I have xentry diagnostic gonna check my voltage on there and I will let you kno also my parking brake handle came off please help senior Leigh

@gregory.baldwin.jr That looks like the cable was broken.

@Senior Leigh | 老李

The cable is not broken to the best of my knowledge when I put my finger in the hole I still feel the cable inside haven’t had time to try to pull it out and hook it back to the handle also When I press the emergency brake pedal it’s not catching anymore it goes down to the floor and comes back

@Senior Leigh | 老李

also senior Leigh when I have a nice load in the trunk usually 100 lbs they car drives really well and it goes straight on the highway? When I remove the weight the car wanders on the highway. could my rear shocks be bad?

also Im getting a shimmy in my steering wheel at low speed 45 mph But goes away at higher speed ? Also when I brake I get a little shimmy in my steering probably rotors?

@gregory.baldwin.jr Sorry for the late reply.

For wheelbase measurement, the absolute value of the measurement is not important, the importance is equal to left and right. You might measure them when alignment or measure them by yourself. 1, keep the steering wheel straight; 2, Measure the length from the center edge of the left and right front wheel hub to the corresponding position of the rear wheel respectively (you might let somebody help you hole the tape); 3, compare the values of left and right wheelbase. If same that If they are the same, it means that the chassis is not deformed, otherwise the suspension system was damaged by the accident.

From the center of the front wheel,

To the center of the rear wheel.

That's the one side of the wheelbase. And then measure the other side.

@gregory.baldwin.jr The method to detect the shock absorber is to press a corner of the car body and immediately release it. If the car body does not fluctuate more than twice, the shock absorber is okay. You might check your shock by this method.

For the steering wheel shimmy at low speed, the most probably is the worse balance of the wheel. Rebalancing them should be good.

For the steering wheel shimmy when brake, the most probably is the rotors uneven. Washing the car immediately after long-distance driving causes sudden cold deformation of the rotors.

@Senior Leigh | 老李

I purchased the vehicle used from a reputable dealership they said the damage was cosmetic and I looked underneath and checked everything and all looks good I also had the vehicle inspected at numerous shops Do you think something is bent or my shocks are bad?

Please help

@gregory.baldwin.jr I consider the most likely is the installation of the strut rod.

@Senior Leigh | 老李 ok sir I did preload the suspension before i tightened the bolt the only thing I didn’t tighten It up to specification I did like 70-75 ftlbs

Normal pressure after driving

The strut is ok if they won't leaking. I feel the W212 is very hard when ride on the pump than my W221.
