Rich Posted May 13, 2014 Report Share Posted May 13, 2014 Strange, I have never heard of that before on a Mondeo. When you changed them were the nuts holding the mount down tight or loose? They had a habit of coming loose when I had mine so I used some thread lock, which stopped it but I never really had any vibration problems.

bojcistv Posted May 13, 2014 Author Report Share Posted May 13, 2014 I have never heard it is like that on any other car mate. On my Mondeo I have had every possible ghosts and gremlins you could ever imagine.... Quote Link to comment Share on other sites More sharing options...
Tony Posted May 14, 2014 Report Share Posted May 14, 2014 I think we call that a "Friday" car in the UK. Quote Link to comment Share on other sites More sharing options...
bojcistv Posted May 14, 2014 Author Report Share Posted May 14, 2014 We call it bit different but the meaning is the same....By the way why "Friday" car? Because workers are in the weekend already and don't focused enough on their work on the production line? Quote Link to comment Share on other sites More sharing options...
Viking Posted May 15, 2014 Report Share Posted May 15, 2014 Yeah, throw it together, get it finished as quick as possible, and head off home. We call Friday "POETS" day. P!ss Off Early, Tomorrow's Saturday. Quote Link to comment Share on other sites More sharing options...
Tony Posted May 15, 2014 Report Share Posted May 15, 2014 That's the one Quote Link to comment Share on other sites More sharing options...
bojcistv Posted May 15, 2014 Author Report Share Posted May 15, 2014 Well workers all over the world are the same Although I don't know if I should blame only them for making "Friday" car (or in France "Monday" car...)....engineers seeds lots of those mistakes into the car construction while they do "blue prints" for them...."It should be good since our calculations says that's is good..."

bojcistv Posted August 14, 2014 Author Report Share Posted August 14, 2014 Hello to all. I haven't been here for awhile but my old trouble rose again. This morning some sort of my allegedly solved vibration came back. Clearly through the floor and seats which means as from rear end of the vehicle. Every thing is fine till 120 km/h and then up to 140 km/h. On increased speed again everything is smooth as silk. Drove back home yesterday afternoon and got out to see if i can see anything odd. Grub the wheel on about 12 o'clock position with both hands and pushed it in and out (in fact what I did was the swinging the car left right with it) and I clearly felt some play in the wheel and through the tyre. Like some knock. I checked steering by laying under the car with my wife's help (she did that in and out pushing the wheel) and i couldn't see is anything is moving. Clearly there is some knock like feeling which made me think if the bearing is in question. But oddly I don't here any sound connected with the bearing failure. So my question to this community would be: "Have anyone here experienced any bearing failure in manner I have just described without humming or grinding noise which is obvious bearing failure sign?" Is it possible that bearing failure in any case could be connected in vibrations that occurs only in certain speed range (like unbalanced tires)? Shouldn't that be in all drive condition when your bearing is about to fail and not only like in described case? Cheers and thanks in advance....

Tony Posted August 15, 2014 Report Share Posted August 15, 2014 Is the play/ knock from the rear? Quote Link to comment Share on other sites More sharing options...
bojcistv Posted August 15, 2014 Author Report Share Posted August 15, 2014 Oh God I have mentioned all but not which car's end is in the issue. Rear end, yes. Left side wheel. Quote Link to comment Share on other sites More sharing options...
Tony Posted August 15, 2014 Report Share Posted August 15, 2014 The bushing that connects the hub and lateral rod is ok i assume? Quote Link to comment Share on other sites More sharing options...
bojcistv Posted August 16, 2014 Author Report Share Posted August 16, 2014 I jacked up the car yesterday and it seems there isn't any play in that wheel. Just that knock feeling and sound associated when shake the wheel while car is on the ground. Quote Link to comment Share on other sites More sharing options...
Tony Posted August 17, 2014 Report Share Posted August 17, 2014 I take it it's a metallic "knock knock" type of sound rather than a thud? Quote Link to comment Share on other sites More sharing options...
bojcistv Posted August 17, 2014 Author Report Share Posted August 17, 2014 Yes thud. I didn't know the english word for that so I couldn't type. Like you are reading my minds Tony. Quote Link to comment Share on other sites More sharing options...
bojcistv Posted August 18, 2014 Author Report Share Posted August 18, 2014 This evening I set on couple beers with my good fella, nice and experienced Ford's mechanic. Told him about my trouble. After an hour we got in his shop and after another half of hour searching for the play in left wheel we found that shock absorber piston has an lateral play! So that is producing that thud sound. Not always, but occasionally and mostly right after car is being driven. Shock as itself is in good condition and we couldn't see it is leaking or something. Just that lateral movement of the piston in its housing. Can that play be the cause of vibrations? I think it can..... Quote Link to comment Share on other sites More sharing options...
Tony Posted August 19, 2014 Report Share Posted August 19, 2014 Yes it could but i'm surprised it's not leaking oil though..... Did you compare the play with the other side? Quote Link to comment Share on other sites More sharing options...
bojcistv Posted August 19, 2014 Author Report Share Posted August 19, 2014 Yes we did. On the right side rock solid. No play or anything suspicious. On the left side there is play in the shock piston you can sense by touch it. Shock do its work well although on some constant little imperfections on the road (surface like tinny waves) some more noise occurs but nothing more.

Tony Posted August 19, 2014 Report Share Posted August 19, 2014 Didn't you replace the dampers and if yes was it just the insert or was it the whole damper? Quote Link to comment Share on other sites More sharing options...
bojcistv Posted August 19, 2014 Author Report Share Posted August 19, 2014 Yes they had been changed back in 02/2012. 56.000 km so far. It was the whole damper not insert type. This is how the rear damper/shock looks like Quote Link to comment Share on other sites More sharing options...
Tony Posted August 20, 2014 Report Share Posted August 20, 2014 Well ok the play isn't right no matter what so i assume your going to replace the damper? Quote Link to comment Share on other sites More sharing options...
bojcistv Posted August 20, 2014 Author Report Share Posted August 20, 2014 Well I am gonna do it as soon as I get some money. Those things are pretty expensive.... Quote Link to comment Share on other sites More sharing options...
Tony Posted August 21, 2014 Report Share Posted August 21, 2014 Wouldn't it be under warranty? Quote Link to comment Share on other sites More sharing options...
bojcistv Posted August 21, 2014 Author Report Share Posted August 21, 2014 Warranty expired in february..... Quote Link to comment Share on other sites More sharing options...
Rich Posted August 21, 2014 Report Share Posted August 21, 2014 What brand did you use when you replaced it last time? The shocks are identical or at least similar to my MK2 and the rears on those lasted 190k miles. Quote Link to comment Share on other sites More sharing options...
bojcistv Posted August 21, 2014 Author Report Share Posted August 21, 2014 I bought Monroe. But I won't anymore...It seems that strange vibration I had noticed back in august 2012 were caused by bad shock definitively. I have managed to make them silenced by changing hydro bushings on the lower arm and top strut mountings but I didn't solve the cause of vibrations. In fact now when I know about that play in rear shock some loud sounds I have noticed during the cold days make sense. Quote Link to comment Share on other sites More sharing options...
