Thread: Why do Landrover UJ's flog out ??

Uni joints has obviously come up repeatedly in this thread, and most replace the LR ones with off the shelf 1300 Series Spicer type uni's.
(Hardy-Spicer part # K5-LR4)

This is a bit of a mistake.

The Land Rover uni's, while matching the 1300 Series Spicer in external dimensions, is much beefier in the cross and the needle rollers are longer than the joint listed above, making it at least as strong as a standard 1310 Series Uni.

The Hardy-Spicer # for this uni is K5-A757
The Land Rover # is TVC100010

I've posted these photo's up in various threads, but maybe more people will see them here. (I pinched the photo's from a thread on LR4x4)

This is a bit of an issue then,
I opened a new "ENGLAND" branded UJ , Part Number TVC100010, Made in EU on box

it looks like the Genuine one above but has plastic thrust washers on the end of the cross



A genuine TVC100010 is 60GBP a Britpart TVC100010 one is 13 GBP,

I'd never cough up $100 for a universal joint but it seems that has been my problem all along. Looks like I'll be forking out for 2 x LandRover genuine TVC100010 , hope that solves my dramas.

As for the Front I'm going genuine too but will keep my 92mm spicer 5-1203x as a spare.

The spicer feels nice & smooth to turn the cups but the "England" one feels coarse, almost gritty

Genuine GKN HD unis are a lot, lot cheaper here than £60

I bought my Rangie classic about 6 or 7 years ago with over 200 000km showing on the non working odometer. The previous owner couldn't recall when the odometer had last worked. I estimate I have done another 150 plus thousand km in the time I have owned it and I have never replaced a uni joint. I do grease them a lot, something I learned when I was working for a remote area tow truck operator.

The 80" and up to series 2 and early series 2a were smaller than the later series 2a and series 3. The early ones used to flog out because they were undersize for the job.

The interesting thing is that genuine Rover Co boxed UJs were about $80 and the same UJ in a Hardy Spicer with a Ford part number were half the price.

I'm not so familar with series drive shafts, but the coil sprung LR and RR used 13xx series joints, some were 1310, then later they were 1300, now from what I have read here the Puma engined vehicles have 1350 joints.

Now 13xx is a Spicer designation for uni-joints and denotes the diameter and length of the actual needle roller bearings. This determines the load capacity (rating) of the bearing, or the life for a given equivalent loading.

The difference between 1300, 1310 and 1350, is how far (radius) the bearings are spaced apart, 1300 being smallest and 1350 largest. This determines the torque capacity of the joint - torque is load x radius.

The next step-up in the Spicer series of uni-joints is 14xx, which have a larger diameter and length of needle roller bearing and increased operating radius.

Landcruisers and Patrol uni-joints are not made to either 13xx or 14xx. I can't remember exact details, but recall Landcruiser joints are considerably larger and stronger than 1310, and Patrol joints are larger than 1410.

The torque rating of 1310 joints is quite adequate for the our vehicles.

The main causes of uni-joint failure is contamination or lack of lubrication. Contamination can enter through the seals or the grease nipples. If the dust, etc. is not cleaned from the grease nipple or the chuck of the grease gun, greasing can result in contamination of the bearing.

Vibration in the drive line can also lead to early failure. As others have mentioned here, high operating angles resulting from suspension lift reduces the bearing life.

I just paid $45 each for the GKN uni (TVC100010) from TR Spares in Sydney.

My uni disintegrated with the bearing caps on all 4 on the cross splitting and all the needle bearings falling out. It's mileage, giving it a flogging and the lift can't have helped.

Hi can you measure the internal bearing journals,there seems to be 2 sizes under this part number,ie. 16mm and 18.2mm.
Thanks Jim.
