jordan_meakin Posted August 12, 2017 Share Posted August 12, 2017 I get a bit of judder coming through the transmission usually when moving off or reversing. I know this can be characteristic of all sorts of things. Some may know from another recent post that I have just refurbed the handbrake, prop with UJ's and rear diff so should be working well. During this process, I noticed that when the rear prop was off, I moved it using just the front wheel drive and it didn't judder at all but when reassembled with new parts, continued to do as before. Does that help to minimise the possible number of causes? Quote Link to comment Share on other sites More sharing options...
AV8R Posted August 12, 2017 Share Posted August 12, 2017 It is not, accidentaly, still in 4 WD ? Handbrake properly adjusted ? Quote Link to comment Share on other sites More sharing options...
jordan_meakin Posted August 12, 2017 Author Share Posted August 12, 2017 No not in 4WD and handbrake is good. It's always done it I was just explaining the recent work that rules out some possible causes. Quote Link to comment Share on other sites More sharing options...
AV8R Posted August 12, 2017 Share Posted August 12, 2017 So that leaves the rear axle then . . . . . With a fresh diff to rule out, how are the hub drive flanges ? Quote Link to comment Share on other sites More sharing options...
Snagger Posted August 12, 2017 Share Posted August 12, 2017 It sounds like a seizing rear brake Iif it was hand brake related, it'd have occurred driving with only the front axles connected too). You need to strip and clean out the rear brakes, and most likely replace the shoes. Quote Link to comment Share on other sites More sharing options...
jordan_meakin Posted August 12, 2017 Author Share Posted August 12, 2017 Back brakes done too - free as a bird. Have no idea about flanges... Quote Link to comment Share on other sites More sharing options...
Snagger Posted August 12, 2017 Share Posted August 12, 2017 I think you have a stuffed rear diff or rear half shafts, with worn or stripped splines slipping, or teeth missing from he ring or pinion. Quote Link to comment Share on other sites More sharing options...
jordan_meakin Posted August 12, 2017 Author Share Posted August 12, 2017 Sounds serious... It doesn't always do it. Sometimes it's fine and to be fair, never severe jumping just a bit of a judder. A friend said it could be engine/gearbox mounts - is that plausible? Quote Link to comment Share on other sites More sharing options...
Cornish Rattler Posted August 12, 2017 Share Posted August 12, 2017 (edited) I always thought clutch judder was caused by the clutch plate now being centered properly, years ago I used to set it by eye and sometimes got clutch judder and since then I just wrapped some tape round a deep 5/8ths socket to center it and never had a problem since Edited August 12, 2017 by Cornish Rattler Quote Link to comment Share on other sites More sharing options...
steve b Posted August 12, 2017 Share Posted August 12, 2017 If it's judder on take up of drive then it's most likely oil on the clutch plates or possibly a distorted driven plate . If the judder occurs once the clutch is engaged then more likely engine/gearbox mounts and/or rough low speed engine running . cheers Steve b Quote Link to comment Share on other sites More sharing options...
jordan_meakin Posted August 12, 2017 Author Share Posted August 12, 2017 Yes its only on the uptake. I had suspected clutch plate but I questioned it as it didn't do it in front wheel drive only. The previous owner replaced the clutch so it is s possibility. I've had it 5 years now so I probably should have done something about it... Oops.

steve b Posted August 12, 2017 Share Posted August 12, 2017 Is the flywheel wading plug hole clear ? , you could always pop the gearlever off and squirt copious amounts of brake cleaner onto clutch through the hole under the front of the gearlever mount . Holding the clutch pedal down would help to get cleaner onto the friction surfaces . A series clutch should last for many years with a std. engine . If it hasn't changed in the time you have had it , then it's probably not a big problem ? cheers Steve b Quote Link to comment Share on other sites More sharing options...
jordan_meakin Posted August 12, 2017 Author Share Posted August 12, 2017 Yes I suppose you're right. It'd just be nice to solve it but not if it means loads of exploring when realistically, it runs well... Quote Link to comment Share on other sites More sharing options...
Snagger Posted August 13, 2017 Share Posted August 13, 2017 I'm working off the information that you only experience the problem when driving through the rear axles, but have smooth drive through the front axle with the rear prop removed. That would suggest there is no problem with the clutch or main transmission, and that the problem lies aft of the hand brake. My previous suggestion of rear brakes doesn't fit because they are present regardless of drive. It would appear to be something to do with the rear diff, rear prop, rear shafts or, possibly the rear wheel bearings reacting to the torque from the half shafts and skewing, resulting in partial seizure. You need to methodically check all of those components for any wear, distortion, play or binding. Quote Link to comment Share on other sites More sharing options...
jordan_meakin Posted August 13, 2017 Author Share Posted August 13, 2017 Excellent - thanks. Haven't checked bearings and that's an easy one so I'll go from there... Quote Link to comment Share on other sites More sharing options...
Retroanaconda Posted August 13, 2017 Share Posted August 13, 2017 Work transmission mounts can cause this, or at least they can exacerbate an existing issue. My money's on clutch, mine used to judder pulling away in first. Changed the clutch and no more juddering Quote Link to comment Share on other sites More sharing options...
