2017 Ford Transit vibration

[andreaskorsnes]

Hello. I have a 2017 Ford Transit van (MK8), 2.0L EcoBlue FWD. At speeds from 30 km/h (approximately 18.6 mp/h) up to about 90 km/h (approximately 55.9 mp/h), I have a vibration from the front of the car that I can't diagnose. It's worst at around 80 km/h (approximately 49.7 mp/h). Above 100 km/h (approximately 62.1 mp/h), it's almost gone. It feels like it worsens on uneven roads. It feels like a vibration originating from the front of the car but felt in the steering.

Both front wheel bearings have been replaced. Brand new tires, I checked the balancing myself and know it's good. New pads and discs. Can't feel any movement in any parts upfront, except for a tiny bit of play in the left tie rod end. Anyone have any ideas what might be wrong?

See this post - link below ..he has a custom ..same engine same drive train ..so relevant to your post.

Note: some recon drive shafts are worse than your originals with crap Chinese CV joint, inboard joint ignored and rubbers and rattle can spray job

Thank you very much for your reply!

Thanks for the link. I forgot to mention that the vibration is completely independent of the engine speed, it only depends on the car's speed. No change with throttle input or turning. It's slightly more noticeable during high-speed braking. I changed the brake discs a year ago. It feels like some kind of oscillation, varying slightly in intensity. Extremely strange!

Do you think it could be from the drive shafts? Driving me nuts.

i could not tell you what it is ..watch the other guys posts he may come up with the answer

Brake discs ..if you regularly brake going down a steep hill steeper than say 1 in 6 for say half a mile or so ,, this will trash your discs in the summer or on hot day... so if you have done that ..don't rule it out .

Light braking, going slow ..if you can hear a swosh swosh equal to each revolution of the wheel ..then your disks are warped .

if the guy who put your discs on, never cleaned the rust off the mating surfaces of hub , then expect the disc to be out of true.

Especially on transits - they can be murder to separate from the hub ..the guy who fitted the discs could literally have used a sledge hammer to get the old ones off ..and ..what other damage or warppage , bending would / could that do ?

Thank you again! I think I'll get the discs replaced, at least to rule this out. I'll report back if it helps.
