2007 2.4 Puma 90
Has anyone seen alignment marks on their prop shaft. If so, where are they and what do they look like. I've taken the rear one off because it's out of phase, yokes should be in line (see photo). Bearing in mind these things are balanced, I don't want to simply line the yokes up, only to find I've got it 180 degree out. I can't see anything to guide me to the correct assembly. There are some marks, as shown. What looks like an arrow on the yoke could also be a capital A  Click image to enlarge Click image to enlarge Click image to enlarge Life is short, so have your pudding first --------------------------------------------- 2007 90 2.4Tdci County HT Stornaway Discovery 1 200Tdi Sold 90 Turbo Diesel HT Sold 110 2.5NA CSW Stolen 88 Series II Sold Meccano Set.

Nothing wrong with the prop shaft other than being out of phase, so it will be put back after greasing and re-phasing. The problem is the apparent lack of alignment marks.

What’s makes you sure out of phase is wrong?
Have you got a vibration? |

On a tdci, the rear prop shaft is also out of phase due to the nose up engine installation. 1988 90 Hard Top, 19J Diesel Turbo, Shire Blue - Restoration ongoing

On a Puma 90, my understanding is the yoke face on the transfer box is considered parallel to the yoke face on the rear axle, therefore they should be "in phase".
The front axle yoke face is considered to be at an angle to that on the transfer box so the yokes should be "out of phase". Last edited by keef9t on 23rd Jan 2025 8:18pm. Edited 1 time in total |

The props on my 110 were are as yours in the picture.. both front and back..
And the gwyn Lewis wide angle that are on now are fitted the way they were delivered ..ie phased Worth noting that the splined joint on the original that I stripped have coarse deep groves with ball bearings...bit like a cv type joint.. so there is not a lot of scope for getting the phasing wrong.. one groove i think sets whats required , as each step is considerably..I forget how many channels around the shaft , but I have pictures somewhere if it helps.. Should also add my wsm calls for a phased prop but again I can't remember if it states the angle.. The originals and replacements have no issues with vibrations. |

I know. Out of phase. It's goofy but that is the way they are supposed to be. So don't fix them!
The real arguments start when you discuss phasing with a replacement shaft that has double-cardan joint added. |

Having said what I did, a quick check on the workshop manual I have, Page 119 fig RR4199 says front and rear should be phased. So perhaps I'm wrong
Still can't see any alignment marks though. |

I'm fairly sure that there are no alignment marks on a standard Puma propshaft, Land-Rover no longer believes that there is any reason to dismantle the splined joint.

^^^^ I believe this to be true, if there are any stamps or markings on them, it was probably just due to manufacturing process. Chillin In The Backwoods🇬🇧🇺🇸

Thanks Dinnu, I think that's maybe where my confusion lay.
Front and rear prop shafts cleaned and greased. Re-fitted to vehicle, as found. |
