Hi, I haven't posted much at all in the while I have been a member here, but I thought I would share this.. and maybe learn from the forum as well.

This is a 200 TDi 1991 HiCap.

It was my truck for nearly 20 years and has been an absolute workhorse throughout my time as a tree surgeon. I decided to show it some love recently with a new chassis, bulkhead and engine rebuild done by Tim Cameron at South West Landys in Cornwall who has done a superb job. It was sitting in a barn for 5 years immobile before the chassis and engine renovation. I decided not to ask him to refurb the lower end / running gear as I wanted to save money on things I can do myself. When I got originally it the front end was really bad..steering slop about a quarter turn of the steering wheel, suspension turret tops sheared of from rust.. it was bad but I rebuilt it all and then some as time went by, so I am no stranger to rusty bolts and moly grease.

Tim delivered it to me pulling like a train and with new chassis and an MOT to drive it to Germany where I live now, but to pass German vehicle inspections the whole of the running gear has to be pretty much perfect, so it is now in a barn for the next month or so getting sorted out. New brakes, new shock absorbers, new bushes and ball joints, seals, new paint, everything.

One thing I am curious about is a 'take up klonk' that has been present somewhere in the drive train since I bought it. It has not got any worse for all the abuse I have given it over the years but I would like to get that gone. I have been inside the front diff once about 14 years ago but did not see much of a smoking gun. Perhaps this refurb might get to the bottom of that..

I will update this thread as the work progresses.. but a major reason for posting this thread is to learn from the hive mind here. I know Defenders are most of the time straight forward tractors, and although I have a reasonable mechanical aptitude there are gaps and limits in my knowledge to do with tolerances and wear and what is acceptable and what needs replacing, and how to know the difference. I would really appreciate guidance and advice from you all, so please sing out!

I am hoping to get an order in for most parts in the UK as soon as possible, then drive over to pick it all up and reassemble it all mid / end January '25. Any help here on what to look out for would be very much appreciated.

Cheers,

Martin.
 
My 110 had a whole load of power take up clonk...

It failed it's last MOT on the a frame ball. I changed that, and a while load of the slack was gone.

The power take up had been bad for years and it only just failed on the ball, so it must have actually been bad for a long time, but the testers passed it anyway.

However, it wasn't all gone, just a whole load bettet.

I then replaced the rear half shafts and drive flanges, and that made another improvement. Not as light and day as the a frame joint, but noticable.

When I get around to it, I'm going to do the cvs on the front, but, really, currently, there's no noticable slack anyway.

Drive flanges are the immidate quick cheap And easy change if there slack in the drive train. They wear to a point and end up with slack between themselves and the half shaft. It will not fix it but they are the easiest to swap for a quick improvement. Next would be half shafts and props (if there is slack in the splines joint, uj slack needs immediate attention!), then it is diffs and gearboxes which are more involved.

The slack is likely to be cumulative so a little bit in everything. From the gearbox to the wheel And even in perfect form I would still expect about 1/8th of a turn of slack in the drive train.
