HD DC or 1330 uni for front prop ?

It seems to be random as far as I can tell.

I have had 2 of these fail, and am now on my 3rd. both times it was the TC end one that failed.

Thanks Pete, I'm not totally losing my marbles afterall :D

What sort of bump stop clearance are you running again ?

Mines dropped a bit over the years, it's only around 105/100mm or so now which has probably saved the uni and probably really shows how little real off road work it's done for a fair old while :angel: Although I snapped another couple of hose clamps retaining the rear springs again this arvo :D:

Will check clearance tommorow as its throwing it down with rain and I can't face going out!

Personally I would probably stay with the basic larger joints just because they are cheaper to replace.

I'll ring and ask re being greasable in situ. There's an access hole in the photo's on the flyer I have, and if you blow it up it looks like there's a grease nipple there.
It'd be nice if you could jam the grease gun in there when doing the uni's, sort of defeats the purpose if the uni's are greasable and it isn't, doesn't it ?

The TD5 Defender just uses a single 1330 uni at the t/case end and a 1300 at the diff end vs 1300/1300 uni's for a Tdi.

The Puma shafts are a totally different length.

Thanks for this Rick. Spicer may have redesigned, though the ones which I have had a hole which passed through into the centre bearing which grease may have been injected into, though the problem is when the DC is built, the uni joint covers the hole and prevents any method which I could see to inject grease into that hole. Perhaps they have a redesign, though what I'm hearing is that the DC's designed with the greasable DC centre bearing has a weaker flange which can be more prone to failure. Tom got around that by using cast steel rather than cast iron - I was under the impression that was a part unique to him rather than a normal Spicer part.

It looks like Hardy Spicer are using a Mechanics DC coupling, not a Spicer for their HD DII joint.

They are using 25R uni's in the DC, and the 25R uni has a much higher torque rating than a 1300 or 1330, even better than a 1410 :eek:

According to the Spicer manual

1300 Series = 162Nm constant, 815Nm short duration
1310 Series = 176Nm constant, 1085Nm short duration
1330 Series = 203Nm constant, 1206Nm short duration
1350 Series = 286Nm constant, 1681Nm short duration

25R Series = 380Nm constant, 1898Nm short duration

FWIW the 1300 uni used in later RRC's, Disco's and Defenders is listed as a Heavy Duty version. (K5-A757)
I don't know if that means longer lifed or better torque rating than a standard 1300 uni.

I think Tombies posted this before, and i did in the lifted Puma thread too

Worth consideration too, although it might be a bit exxy from the UK. Someone here could fab one up pretty easily.

Some interesting info there, esp the strength of the 25r joints. They would still be limited by the joint the other end I guess.

regards bumptop clearance on mine, I checked earlier and it was about 135mm.
