I have 14 grease fitting on my 2009 HH there are 6 fitting I cannot get grease into them. I bought a tool called "Grease Joint Rejuvenator" used to open cloged joints. What kined of oil is good to break down old grease. Some one told me brake cleaner, or is there something better than that. I got it from Northen Tool not cheap cost $40.00. They list it on the bill as "Grease Joint Cleaner". Any kind of help will be good.

I assume that your fiver has the shackle bolts with the grease fittings on them. I think these are a good idea. I put them on my fiver several years ago. I grease them every spring before our summer trips. There are always one or two that won't take grease. I found that I had to jack up the frame and take the load off the shackle. Then lossen the nut on the grease bolt and give it a couple of turns with a wrench. It will then again accept grease. I guess the little holes in the bolt get clogged.

I'm going to assume your talking about the suspension zerts. Did you lift the trailer to remove the weight? Real common to have the weight of the trailer blocking the grease port not allowing it to flow. Randu

I will try one more thing before I jack the tr to take the weight of it. Someone told me brake cleaner might work, then maybe hydraulic oil. Thanks will let you know if it works.

Not a good idea to turn the bolts as they are splined and pressed into the shackles. The purpose of the splines is to cause the movement of the suspension to take place between the bolt and bushing, not the bolt and shackle.

X2 turning the bolts is a sure way to cause a failure of the bolt and shackle.
I do not understand the reluctance to just jack the trailer and grease with weight off of the bolts. Seams to me a easier way and less danger of destroying the lubrication properties of the wet bolt. Once you have brake cleaner or hydraulic oil in the wet bolt how do you get it replaced with grease?
When I installed mine I took a Dremmel with a 1/8 HSS ball cutter and grooved the interior circumference of the bushings, indexed with the grease hole in the bolt. Grease goes in much easier.

I'm with Grey Fox. I put in wet bolts and one would not accept grease. Mfg suggest the bolt get backed off a bit and turned a little (not easy). It did and it now accepts grease. Apparently I did not put it in correctly for the internal grease hole to align with ???.
