Vibrating/rough pulling

Post by 8bit-ash on Mon Jun 17, 2013 8:33 pm

Havn't had the chance to get under the van to have a look yet but since I did a couple of 100+ mile drives over the weekend the van has developed a fairly bad vibration type noise/feel.  It seems to be much more prominent when accelerating under load and feels like its transferring through the driveshaft/axle.  Anyone experienced this?

Nope, but my first look would be at the propshaft, as maybe the UJ had failed and was really stiff.

Logans prop shaft failed but just made noise, although they are very common failure item.

??? The million dollar question.

On the good side though, you can get the prop shaft off in less than 10 minutes and you don't even have to jack it up like a normal car.

Well that is unless you've lowered it like a ricer Wink

Its your propshaft on its way out Ash. Get underneath and check the joints for wear and as HJ says easy enough to drop the prop. 
I have repaired hundreds -- in fact over a thousand Staked Propjoints on Fords, VW Transporters, Transits BMW's and other RWD vehicles. In one case on a Mk2 Escort the front joint let go and the prop dug in the road and flipped the car over and wrote it off. 
that cant happen on a Hi-Jet as the prop is too short but it can take out brake and fuel lines and make a right mess off the floor pan. 

I have seen that on numerous occasions. If the rear one lets go on a Hi-Jet the prop will fall 
off as its on a sliding spline and that happened on a Cortina and it hit the car behind.

I am going to contact the Company I used to deal with and see if they can supply Staked Joints for Hi-Jets and if so I will do a replacement service on Hi-Jet props. 

Will keep you all informed. Please check that prop out before driving it again Ash.

There is a 20mm difference in length, and not interchangeable. The Pickup prop is 340 mm centre
to centre of cups and the vans are 320mm centre to centre. Doesnt sound a lot but the longer prop on a van when under full load of weight can damage rear of gearbox.

Well its definitely the prop shaft -



Hard to tell from the pic but don't think it was far from detaching.  Which are the recall ones the ones with or without the sirclips?

Well  I am glad you took it off Ash. You are lucky in that you have got replaceable joints rather than Staked joints-- provided you can find a supplier 
of the circlipped joints.

I have found my WHOLE Staked Propjoint Replacement Kit for all 3 sizes of joints, 22mm, 25mm and 27mm. It cost me over £600 0ver 20 years ago.

I will try and contact my old supplier and see if they can supply the Hi-Jet Joints--- if so we are up and running Baby-- A Hi-Jet propjoint replacement  service.

And just incase, but I'm sure your clued up already - I fit UJ's in my vice at home with no problems. No special tools needed, just some ye-olde techniques, using sockets and the vice.

Got the UJ off today, the ebay ones don't seem to measure up to mine according to those measurements in the lithuanian site. Crying or Very sad
May have some progress with the recall though trouble is I need it for next weekend.

Others list it as 59mm x 23mm

UJ's are measure with the caps on - so total width and cap diameter.

This might help you find it too:-

I am hear to learn as well as help, I know prop shafts fail fact but this is bugging me,

If the van shaft is longer by 20mm and the spring hangers are longer on a van by 20mm than on a pickup, if the van is lowered and the prop shaft not shortened would that put extra strain on the uj or am I am going daft?

If anything theres probably less strain on mine as its a straighter path from the gearbox to the axle.  Thats my thinking anyway.

The pick up chassis is different and the travel of the sliding part of the prop is relative to the amount of maximum travel so unless you notch the chassis it won't make a bit of difference.

I can see that angle getting less which is better

Sorry not getting this and not doubting you either

Prop slides in and out with axle travel agreed, so if the axle is moved closer to it's upper most position when hitting a bump would it not go past the point where it would have maxed out before in the original position, wouldn't the prop to be shorter?

Hiker prop shafts were made with cheap crappy UJ's it would seem, just like the thermostats.

Hi dinoh. See you are struggling with this one. If you look under your van you will see that the propshaft because they are so short, sit at quite an accute angle. As the axle travels upwards ( or the body downwards ) it prescribe an arc from
the front spring mounting on the chassis causing the prop to move forward .
To see for yourself get a few friends to sit one at a time in the back and watch the body come down further and further
and just see how much it slides further into the gearbox. You may get away with the longer prop but I wouldnt chance it.
Also the whole axle moves forward too when you give it a real bootfull . If you are really travelling at speed over a bad road surface that could also make it move further forward or backwards too.

Thanks Woody

100% undersand that but been tryng to put in to words what Im trying to ask
Here goes
At what point will the prop bottom out, lifting the axle higher from the standard position would it not get closer to the prop bottoming out?
