2004 2.5CRD Juddering in reverse
 

Hi there,
Thought I'd throw this one by you guys.
My 2004 2.5CRD has developed a judder in reverse, sometimes so bad you have to slip the clutch to get it to move.
It all started one day down a narrow lane, when I selected reverse the engine tried to get out of the bonnet, well that was what it felt like.
When I got home had a look underneath and found the front lower engine mounting bracket had broken, took it off and welded it back together and fitted a new mount at the same time, thinking that'll sort it.
But it didn't, problem seems to get worse once the engine has warmed up, reverse seems to work OK, at least every time i try from cold.
It really shakes around, had a look at the other engine mounts, which all seem fine, not to sure on the rear one yet, if you know these engines its a bu**er to get at, and will have to wait a while.
Have got a bit of an oil leak between eng/trans, not a lot, but wondered if this could be part of the cause.
Seems odd though that before mounting broke not had any problem with reversing.
Anybody got any thoughts before i rip it to pieces

Many thanks

Andy

I have a 2000 model, so the older engine to yours and the mounts seem to go after +-70K rear and front. My personal experience is that once one mount goes you need to replace all four and then provide a bit of front bias before torquing them all up. i.e. raise the front of the engine slightly. This partially cured my reverse vibe issue. Geometry is defo the issue here. Even though we have different engines they are both built around the same VM425 block. I can get to and remove my rear mount without removing the transmission so you should be able to as well.

The oil leak is a common issue on these cars and is the rear crankshaft seals. You have 3 on your car 4 on mine.

How did you get on with this problem?I have exact issue, we have already fitted new clutch (:mad:and if anything its worse),also replaced the front mounting.
The judder is also present in 1st when pulling off but reverse is wild,can also feel slight judder when dropping down through gears

Still got the problem, lived with it till now, but must sort as feel its getting worse, think I've tried everything I can to no avail:mad:

gearbox
 

Hi could you tell me what you have tried so I can stop throwing money in wrong directions,Did you change all the mounts?On the verge of trying recon box .do you have any other issues with the gearbox?difficult gearchanges crunches etc.

Juddering
 

Hi Chris
Front and rear mounts changed, had already fitted replacement gearbox as mine was broken but way before this started.
Have slight oil leak in clutch area which 'might' be helping problem.
I have no other issues with g/box, but do feel juddering if pulling away, especially up hill. Feels like the engine is going tofal out in reverse, and cannot reverse up hill at all.....:mad:

exactly same problem.
 

Hi Andy,Yes mate we definately have the same problem.
I booked it in to have rear mount done at a mates garage this week,the part alone was going to be £200 plus vat from lookers liverpool (chysler dealer),none of the lads fancied doing the job as the rear mount is a pig of a job!
They soon convinced me it would be a waist of money as they believe a broken mount would not cause judder ,A broken mount would causes a jolt then once it bites your away ,you would hear & feel a bang every gear changeas etc etc..
Their opinion however is a lot more worrying.they showed me a taxi engine block (head off conrods exposed) on the floor which had a lot of play(visable by pulling and pushing flywheel.
He believes that the judder is basically the pressure from clutch pushing the the worn crank,the judder is the strain on the con rods fighting against the clutch.(mine is definately worse since new clutch).
How many miles has yours done?.mine is showing 132k
He does a lot of work on black cabs and says the symptoms are the same as the worn block he showed me on the foor.
I asked why doesnt it do it whist going right through the box,he says the strain is obviously heavier from a standstill!
Another opinion which i believe less is a warped flywheel?I reckon if it was a warped flywheel you would feel wobble through clutch pedal.
I am still not 100% convinced as the engine sounds great no smoke etc
I have a reasonable understanding with mechanical side of things and my gut feeling is play in the the gearbox rather than the engine.Next day off and im gonna go to a few gearbox specialist
I have done 600 mile in it this weekend and it does my head in,you can slip it pulling off and its not too bad ,i can feel it now coming down the box 4th -3rd,3rd-2nd,reversing a embarassment.
I will let you know how i get on with gearbox experts.
Regards Chris..

Hmm thats a differnet slant on the problem, hopefully not ours.
Mine is a bit higher mileage than yours 206k....
But as you say pulls well uses no oil returns reasonable mpg so don't think thats the case.
Done a couple of tests over the weekend, and found that when cold, ie standing overnight I can reverse without any judder.... although its not much of a slope up, so still iffy on that.
Once done a few miles forget reverse, as you say embarrassing.....
I just can't get my head round that it started when I broke the front engine mounting bracket, all was fine up till then, now I am lost still suspect rear crank oil seals, but why only after bracket broke...
Ah well one day I may fix it, just to many other things on at the moment to spend to much time on it.
Regards

I have a Grand Voyager 2.5 CRD 2001 (newer shape) and have clutch judder when pulling away, and has got worse with new clutch. When the clutch and flywheel was replaced today, there were bolts missing from gearbox, meaning the engine and gearbox had become separated. The mechanic who just fitted the clutch couldn't understand why these bolts had worked loose, but could it be to do with the theory that "the pressure [is] from clutch pushing the worn crank,the judder is the strain on the con rods fighting against the clutch".
We just want this sorted, and would ask whether one or more engine mounts should be replaced, or it is likely that the problem is in the engine or gearbox.

mmmm thats abit worrying mine judders a bit 2002 grand voyager 177.000 miles goes ok doesnt smoke or lose oil
