Help ! Propshaft uj replacement mk5

[vanfox]

OK, I'll investigate as to why I found ring grooves.

[vanfox]

I wuz wrong....there are no grooves in the one I just sawed apart, just the yoke peined over. Sorry, as they say, my bad.

Welding cups to forks is a common way of fixing cups after replacing crossings in such cardans.
This is not a good idea.
The best would be to remove the metal forks level with the cups and weld to the forks rings with a groove for the locking rings.
And only after that start the replacement of the crosses.
Otherwise, the misalignment of the propeller shaft parts can not be avoided.

Changing UJ's with circlips is easy enough and there are videos on you tube if anyone hasn't changed them before, but the problem with most transit propshafts is they don't have circlips, so its either take it to a propshaft specialist, buy a second hand part, or weld a ring to the yokes to allow circlips to be used.

I found an old thread with a picture of welded in circlip ring.

I found an old thread with a picture of welded in circlip ring.

Approximately so I suggested.

[cherniy_chack]

Usually they do so. I do not like it.

I just welded the mud-reflecting washer in front of
suspension bearing.

Welding the U-joints? If no circlips on the outside, are there no c-clips on the inside of the bearings?

Like these ones?

Hi ,ive actually got a great deal of experience in this exact thing. I live in the remote jungle in the philippines and was forced to fix my stuffed Prop Shaft U joint myself. I first attempted what locals told me to do, which is what u see pictured everywhere, cutting the cross bearing with a grinder, pushing the caps out through the middle, grinding the stakings down with a small grinder stone on a drill and then tried to get a proffesional welder to just tack a few spots to hold the caps in place with washers in to protect the cabs and grease from the heat.
It lasted 1 week.
Its impossible to centre a cross joint properly in this manner. It just shakes itself to death within the first week. it has to be perfectly balanced and centred.
The solution, i came to after 3 attempts and lots of hair pulling, was to give myself the ability of adjusting the centre or the shaft while installed in the vehicle, using the vehcles drivetrain setup to help me to line it up.
I did this by assembling the U joint, and lightly welding nuts to each face of the 2 yokes. Then i screw a bolt (with an extra locking nut on each) through the nuts and get it roughtly centred to the eye.
Then i installed it in the car, jacked up the rear, and started the engine in 1st gear.
U can see the prop shaft moving up and down like this and this is the alignment problem we need to solve to stop it sahaking itself to premature death.
To solve it, I placed a marker pen in a locking grips and gently pushed it towards the rotating crankshaft covered in duct tape (so the pen would be clear) and watched wher ehte high spots would mark. The pen markins on one side means the shaft needs to be moved to that side. u do that by adjusting the bolts.
Here is a pic of what i like to reffer to as my FRANKENSHAFT.

This has been going fine now without a noise for about 2 years.

[rebuilder86]

if your going to repair a staked in joint, in my experience this is the only thing that works.

Nice

[cherniy_chack]

Kjeles ,there are such crossings, but the internal dimensions of the forks do not correspond to them.
The idea of rebuilder 86 is good, but it requires a lot of effort for execution.
Suitable for poor countries where there is a lot of time and little money.
Is Britain like that?
Even I in Ukraine will not do so, my time is my money.
It is easier and cheaper to buy another propeller shaft.
Or maybe I just became old?

[Chug]

I agree Cherniy, a full secondhand propshaft in good condition can be £200 in the uk, or any one of the three individual sections can be bought for £70, sometimes its possible to find them a little cheaper but maybe in not so good condition.

For not having to take the time off work for most people here its cheaper to buy a propshaft and so be able keep your work going to pay for it and not have to spend days trying to do it yourself, maybe those without work might be willing to take the time and effort.

The front sections for 3 section propshafts are getting harder to find here now.

Individual UJ's can be replaced with new ones by professionals over here for around £100-£150, but unless you have a professional nearby, or a good friend to take you and your propshaft to him, you will have to pay postage costs for a heavy item so secondhand is popular.

[rebuilder86]

Well, this is all true, but OPs request was for advise on how to replace it hinself. Im just answering that.
In the jungle, it took me all of 3 hours to dissasemlble, weld, and centre mine in the blistering humidity and rolling around in dirt haha.
It should be relitively simple with a nice clean flat working space.

[cherniy_chack]

rebuilder86,there is such a Russian proverb: the poor are rich in cunning.
And further: you want to live,be able to twirl self.
We are not in the jungle, Britain is one of the pillars of the modern World.
It's easier to buy than to do with your hands.
I found in Poland two sellers of new long three-link kardans.
One in the photo has snap rings, for the other there are no such photos.
The price is about 200 pounds sterling.

Buy in Britain will be cheaper due to shipping.

[rebuilder86]

Fair enough.
A single cross bearing would surely cost less than 30 pounds? And the cross joints are really the only part that wears. So by replacing it, u effectively have a new part.
I see it as an economically viable decision.
