In the process of replacing my two rear UJs after forum member JayGti kindly pointed out it might be the cause of my slop/noise/clunk in my driveline. Having got it off and been able to properly look, it’s clear it was in a very, very bad way, so thank you to JayGti and this forum for all advice so far.
Completely covered in gunk. (From now on I’ll certainly do period checks/cleans of this area)  Click image to enlarge Click image to enlarge Rusted beyond belief Click image to enlarge Click image to enlarge Sheered-off end cap Click image to enlarge Finally, the muppet who fitted the previous UJ seems to have either hammered the older UJ out and damaged the prop shaft UJ housing, or hammered the c-clip back in, achieving the same damage. Click image to enlarge Either way, the track to house the c-clip is almost flat for about a fifth of a turn. Clearly this poses an issue for the new UJ as the c-clip will never be seated properly. A shame as the prop and splines at the transfer box end are in very good condition. So a number of questions arise: 1. Is it worth trying to get the track/prop end repaired, given the track is almost flat? 2. If not, and a new PS is needed, is there any advantage to going HD or Double Cardan (approx £200 more than a standard GKN replacement), if I do 90% road miles, with what will be at most (for the foreseeable future) a 2.4Tdci with perhaps a BAS 175bhp tune. 3. Finally, I still need the Def, and the part might take a week to get here, is it OK to drive FWD only? Thanks all....  Monsieur Le Grenadier

Thanks JayGti. Indeed I was just about to head out and try exactly what you recommended and go from the there. The prop is very serviceable otherwise, and only needs a good clean. Thanks for the advice on regressing, noted. I do mostly road KMs, but also live in a place with a lot of snow, mud, rain etc. So 6 weeks seems sensible and now I know what I’m doing, easily achieved. Better than driving around with 2WD (thanks for that info as well).

I'd say that circlip seat was done in by removal of the circlip in the wrong manner or hammering a punch or blunt instrument around it instead of using circling pliers.
I do mine every six months now, its surprising on servicing it seems to me they aren't touched at all. It's mainly wading that they need to be looked at a lot with. No Guts, No Glory. 🇬🇧🏴🏴🏴🇮🇪🇺🇸⛽️🛢️⚙️🧰💪 |

Wading won't hurt a greased UJ, they are sealed after all. The thing that kills them (as jaygti says above) is not greasing them frequently enough so that the old grease dries out and new grease can't get in. Then they will inevitably self-destruct quite quickly.
I have actually seen far, far worse than that pictured above over the years. If you have to buy a new front propshaft then personally for a TDCi I would recommend a DC joint on the transfer-box end, since it will help with the generally cattywumpus geometry and will reduce vibration (the front of the t-box is cocked up in the air, so the two flanges are not co-planar). However they are a bit pricey. At the rear, the question of a DC join doesn't arise. Should you fit an HD prop on the rear? Unless you work the vehicle hard I don't feel it is necessary. An HD prop will probably have larger UJs, but these will fail just as quickly as standard ones if you don't grease them. So for most vehicles a standard rear prop is quite good enough if looked after. |

Thank you all.
I’ve taken apart, cleaned and prepped it ready for the new UJ. All good. But on getting to the front (transfer box end) of the PS I’ve found that the UJ is a good 2mm wider (circumference of the end caps) and has a larger body as well. I was led to believe by the supplier that they would both be the same. Is this the case, or are the two different sizes normal? If so, anyone know what the part number is?

Thanks DorsetSmith. Yes, the listed part looks the same as mine. Just wondering why, therefore, the UJ supplier didn’t tell me I needed two different sizes of UJ for the front and rear sections, unless mine has been adapted somehow. But looking at the photos it looks identical.

I was under the impression Pumas have different UJ on the front prop compared to the rear, but each prop has 2 of the same. I’d be interested to know if this is wrong, as I carry spares for long trips and want to know I’ve got right ones. 2007 110 TDCi Station Wagon XS

Honestly, I don’t know whether your impression is right or wrong, or if I simply have a different UJ head on mine to a standard GKN made post 2007 PS. As far as I can tell my prop is as presented by DorsetSmith. Post 2007, tapering at the transfer box end, but it seems that it might have a wider UJ mounting than standard at the transfer box.
Basically I’ve measured as follows: Front, transfer box end, 95mm. Rear, diff end, 75mm. So I’d strongly suggest actually measuring yours at both ends (Fnarr, fnarr  ), to be doubly sure.
I had come across the odd thread saying different sizes at each end, but supplier said the same at each end. Another week’s delay Monsieur Le Grenadier

I have never come across a Landrover propshaft where the two UJs on the same propshaft are different sizes, that is wrong.
On a TDCi 90 the front and rear shafts both use two TVC500010. TDCi 110 (and I think 130) use two TVC500010 on the front shaft only, and two RTC3291 on the rear shaft. TVC500010 is approx 95mm across the flats of the cups, and the cups are 30mm diameter. RTC3291 is approx 75mm across the flats of the cups and the cups are 27mm diameter. It sounds to me as though someone has taken the long bit of a 110 propshaft and the short bit of a 90 propshaft and fitted that result to your vehicle. I do have a spare rear prop for a TDCi 110 which I am intending to advertise on here shortly, but I suspect that I am too far away from you for this to be a sensible option! As a curious aside, it is interesting to note that the RTC3291 was also used on Series 1, 2, and 2A vehicles up to 1964. Strange that the last and most powerful version of the classic Landrover reverted to the same UJs as the first and least powerful! It make you suspect that it was over-specified in 1948 and under-specified in 2007. |

Thanks Blackwolf. It did seem odd to me. You’re more experienced than me, but any reason you can think of why this might be the case? Also, any reason you can think of why I shouldn’t keep using it in this configuration? It’s actually in good nick. But if it’s not right, then perhaps your rear PS would be welcomed. As it happens, I work for a UK company that ships stock regularly from Cornwall, I could have it brought over from there with their next load. But, back to the original thought, any reason why I shouldn’t just buy a 95mm UJ and pop it in?

Actually there is no reason that I can see, and it would give you a larger (and hence stronger) UJ at one end of the propshaft. I suppose that it is possible that this is why someone has done it in the first place.

Thanks. I think I’ll pop the 95mm in and get it back on the road asap. Ta Monsieur Le Grenadier
