Double Cardan Joint......

[cpeters]

I now drive a 2010 swb 4x4 and the first two dealers I have been to can't find anywhere to lube the front shaft... . I even pointed out the sticker under the hood where it states the need for lube, Does my truck not have a lube point? When did they change that? Also first dealer swears he is not supposed to pre-fill oil filter and second one did? I always have but wanted others opinion.

The grease zerk is a recess style of fitting. If you had the standard style of grease zerk this would be broken by the CV Joint movement. You need to have a different style of grease fitting on your grease gun to press the recess ball in the zerk to grease the drive shaft. Most dealers on their lube rack do not have the fitting available.



As a side note I went round and round with the Chrysler dealer after the Dodge dealer was closed. They claim that the CV Joint did not need greasing and Ram had designed this out. I proceeded to inform them that I am a retired engineer from Cat and I know all about CV Joints. I then showed my dealer where the fitting was, his answer was oh well can't grease it since we do not have the adapter. Now I service it my self.

When you do it yourself do you need to jack up the front end or just the drivers side to rotate to get at the fitting?



Got the Grainger adapter for the fitting so I am ready to go.



Thanks

Do you have the part # for the adapter?

You can Jack up just one side.

Thanks. I'll give it a shot. It has to be better than the needle I have been using.

The Grainger part number is 4ZT24 Coupler Needle Point

Hi all,
Replying to old thread to help anyone who needs it.
I had a 78 Chevy Blazer when I was a youngster, which had the exact same double cardan joint configuration. i used both style adapters over the years, both have shortcomings; tapered style leaked (was fussy) and needle style was too easy to bend or break. Recently tried a disposable 5CC syringe and an 18 ga blunt needle. Wow how simple and superior to the other systems and just $3 to boot. Tackles the need for 3 hands, small and light-weight so the needle is less likely to bend/break, and clears under vehicle obstacles with ease. Finally, 3-5cc is the perfect amount to SEE going into the joint. Got rid of my adapter, never again. Farm and Fleet, TSC, Rural King, etc sell syringes and needles for cattle. You can get blunt needles for gluing applications easily online. Size will be 18 gage, maybe 20. Good luck.

Wow... Thanks for that. I didn't see a zirk, and asked the dealer, they said it's new sealed bearings that don't need grease, I left it at that.

The adapter is a shaft about 2 inches long, and about 1/8 inch wide with a tip pointed at about 60 degrees, any good auto parts store will have one, once you locate the button to add grease, take a paint stick and mark the drive shaft with a long arrow pointing to the spot for future servicing
