Hi all again, I have a 100 series standard 4.2 L diesel Landcruiser built 1999 (the type with the barn doors). I have struggled over the years to grease the rear CV joints on the drive train. In the end I have had Toyota do the work fro me.

I have tried different combinations of jacking the Cruiser up to try and open up gap without success. I have even ground down the grease gun nozzle. I'm a fairly green back yard mechanic so this request may appear absurd, however I have the wall on ideas.

Is there any easy way to do it. Is there a narrow head grease gun nozzle on the market that suits.

Hi Nobby. I presume you mean the rear tailshaft UNIVERSAL joints. If so you need to have the rear suspension at the bottom of its travel. In this position you can turn the tailshaft so that the joint is more open in one area enough to get your grease gun to the grease nipple. The other way is to unbolt the rear flange and release the tailshaft. Cheers,Bob

You may want to check out www.lcool.org/forum . There are a number of discussions about lubrication of cruisers and what grease to use etc.

Macnaught and others make a long needle injector. About $40

The problem is with the angle to get in to the nipple, I have similar problems with nipple on front of transfer for front shaft as well.

good luck

Some of the cheap replacement nozzles are smaller and fit in easier.
I've not had trouble, but a friend came over with a new Toledo grease gun, and had the same problem as you. We swapped the nozzle for the smaller one that I use and it was all good.

And just to add, never put more than 2 pumps into the sliding yoke, otherwise the prop shaft pushes hard between the diff and transfer and can cause vibration and pressure on the flanges.

Im not sure how this is possible, never heard of it before? The grease should squeeze into the splines and it should not be possible for it to "pressurize" behind it?

fisho64, Phil G is correct - This is a well known issue if you over grease the 100s

Go for the Mcnaught Needle as previously mentioned.
I had the same problem for years, patiently rotating a wheel until the gun would fit into the gap.
Untill I met a McNaught rep parking his car outside the local tool shop. Upon discussing the problem he took me into the shop and took a McNaught needle of the shelf and said "you need one of these"
Now universals get greased after deep water crossings while on the road --- easy as.

I've had the same trouble greasing the front uni joints on my GU Patrol; the gap in the yokes is not enough to accommodate the grease gun head.
I've ground a couple of flats on the head of the grease gun to allow the head to fit in the tight space between the uni yokes. Even then, there is only a small angle of rotation of the front drive train which allows the head to fit properly onto the nipple.
Be careful to only grind off enough metal without cutting thru the head!

Nobby
Mazda Bravo,s have the same problem, you need to buy the smaller size nozzle for your grease gun. In the Bravo's case I also had to buy a pump type gun [fill tube with grease ,screw on cap and push on tube to operate] as a grease guns nozzle tube was to big to fit into the yoke of the uni.
