This is my first post, so hello everyone.

I am after a bit of advice about my 2011 1.6TDCI Fiesta, I am having a bit of a nightmare with it and its a semi long story.

Last year I took the car off the road to replace the front droplinks, bottom balls joints and track rod ends. Also while the car was up on stands I decided to renew the CV joints to, semmed like a good idea at the time. So I got to work on both sides and removed the parts except when I cam to remove the CV joints from the hubs on both sides the were stuck so bad I had to remove the wishbones with them them. After seperating the hub from the wishbones I then still could not get the CV joints to come out from the hubs, I tried everything I could think of including heat, soaking in all sorts of chemicals and even bought a puller to no aviail.

Heres where I think i may have made an error, I decided to just bin the old hubs and get second hand replacements as there not exactly expensive. I ordered some from ebay and they turned up and I fitted them to the car and renewed the CV joints, drop links, ball joints, track rod ends, discs and pads. All went together fine and the car was finished, or so I thought. I tried to move the car, being on the drive I had to reverse first, the car moved backwards ok but when I went to move forward the car wouldnt move at all so had to push it back up the drive.

I think the error I made was buying hubs and cv joints for any old 2011 diesel fiesta, after researching it seems the 1.6 TDCi has slightly different hubs. I ordered the correct hubs, and brand new driveshaft for the drivers side specifically for my model and fitted those only to the drivers side. I thought that the car would move ok and then I would do the passnger side next with the correct 1.6 TDCI parts but the car still wont move!

I was just wondering if anyone has any ideas about why the car wont move after putting the 1.6 specific parts on one side? Is it to do with the diff or something else?

Anyway, sorry for the long winded post but I wanted to give all relevant info I could think of.

Thanks! Chris.

If there is a problem with the passenger side driveshaft then the car won't move. The problem could well be the driveshaft is not fully engaged and therefore it's just like that wheel is spinning on ice. The differential will always transfer power to the wheel which has least grip, or in your case easiest to turn.

Thank you for the reply. I thought the car would move with the one side done? when I put it in gear and try to move the drivers side is now quiet and the spinning noise is on the passenger side, it was both sides before. So I should go ahead and put the 1.6 specific parts ont he passnger side too?

Yes.

You have to have working drive shafts on both sides otherwise all power will be sent to the wheel that is freewheeling. There will be no drive power sent to the good driveshaft.

On true 4 wheel drive cars with manual gearboxes, you have a selector called 'Diff Lock On' this basically means that if one wheel looses traction, the drive will still be sent to the other wheels. With diff lock Off drive would be sent to the wheel that had lost traction and there would be no drive sent to the other wheels.

That makes sense now why the car isnt moving, I will change the other side over the next few weeks an report back.

Thank you very much for your help, it really is appreciated 🙂

Just wanted to update this thread, I have now replaced the passenger side driveshaft with new cv joint etc and its all back together and its all working on that front.

So a big thank you to unofix 🙂

Next up sorting the P0299 underboost issue, oh the joy 😄
