I attempted to search this, but I couldn't find any previous discussion. I have been slowly catching up on the neglected maintenance on my new-old 89 pickup. I was greasing the drive shaft, but the jerk fitting on the rear u-joint is in such a position that I can not get the head of the grease gun on it. Is there a trick to this or something ? I have had no trouble getting to the others...yet.

I have the same issue. I've tried a needle greaser and the grease just comes out aaround the needle. I've resorted to just not greasing it and just replaced it with a lifetime warranty one it starts squeaking i replace it for free.

I've never had a problem greasing that joint. It's pretty easy actually. Just get a flexable hose grease gun and clean off the zerk and fill it up. Done!

Mine isn't that simple, it appears the zerk fitting was installed in such at way that the tip of the grease gun will not fit onto the zerk fitting. The ears of the shaft are in the way when trying to fit the tip of the grease gun onto the zerk fitting. I probably sound like some idiot , but I have never ran into this before and was curious as to if mine was just the odd ball that had the zerk fitting installed funny or if this was a common issue that someone had figured out.

The zerk on mine is between the 2 caps not in the center of the joint or on the cap lik every other joint.

Only 4 bolts to remove that end of the driveshaft, then you can turn the ujoint however you need to ...

Maybe a n00b question, but whenever you remove this, you're supposed to label and re-attach the flange/yoke with the exact same bolt holes aligned, correct?

Does it matter?

correct

The driveshaft is balanced as a single unit, so, yes.

You probably already tried rotating the driveshaft to different positions, which often will give access. But if not, give that a try.

If there's no position that gives you access, then perhaps someone previously pulled the driveshaft apart and reattached in a different position, blocking access to the zerk? It is highly unlikely that the truck came from the factory with the zerk in an unreachable location.

Also, some grease gun fittings are smaller than others; might try a different gun.

chok the front wheels, lift the rear axle up a hair, and with the tranny in neutral you can spin that sucker till its easiest to reach.

I'm thinking someone put the wrong fitting on it when the shaft was off the truck!

Uhhh...
When you take the rear driveline off the diff, it doesnt matter what holes it goes back onto..
Now, if the driveline is out of phase, then thats a problem.
Just unbolt the bolts off the driveline

Only if you take the slip yoke apart - which you shouldn't need to do to grease the ujoint.

Toyota has a couple different bolt patterns, some of which are very near (but not) square. To make sure I don't have to fiddle with it, I try and put the driveshaft back onto the flange in the same orientation it was, the dirt/grease usually mark the flange pretty clearly. Worst case, you have to turn the rear pinion 90* to get the holes to line up.

My rear U-joint is the same way. I can't get my grease gun tip anywhere close to the zerk. I had to replace the U-joint and had the driveshaft out of the truck and still couldn't get it greased. I also tried a needle but it didn't work. The CV ball & 2 u-joints on the upper half were easy to grease. I guess I need to find a smaller attachment for my grease gun.

FleshThorn

I noticed that the forward u-joint on the rear shaft has a angled Zerk fitting and there is no problem getting it greased. Maybe I will attempt to replace the zerk with an angled one. Would probably be easier than waiting for the universal to go out.

ive never had a problem using a grease needle.

how do you go about using one without the grease just squirting out around the end of the needle? if i understand correctly, the needle is supposed to sit right on the ende of the zerk, push in the spring loaded ball on the zerk, and you just keep pressure on the needle? any tips would be much appreciated, i am having the same trouble, where the fitting is between two sides of the plus sign, such that the shaft and yoke ears block the gun fitting from going in.

thanks guys

When the U joint was replaced it was probably installed backwards so now you cant grease it. dont ask me how i know.....

ilostmypants

do this but use jack stands. it should work. hopefully your grease gun has a flexible hose and a one handed pump or else it can be anoying to hold the gun and the hose and pump the grease.

Jay351

Yea you need to keep constant pressure on the needle or else the grease won't go into the fitting.
