I just finished installing a Crown HD drag link and tie rod assembly and noticed 3 out of 4 grease boots won't take more than a squirt or two of grease. Usually I'm able to force out the old grease but my gun won't even pump with these. The 4th boot seems to be normal soft rubber and functions/expands like normal, but the other 3 seem to be made of harder, inflexible material, and have some raised ridges on top.. What's the deal with these?

Had the same issue with Crown parts. Hope I can get some grease in there after driving around a while. Also had under sized zerks that didn't seal well on the grease gun .

Very interesting... I did try a new zerk on one of them but it behaved the same way. I wonder why they have the weird boots and if that has anything to do with it.

I don't think the boots have anything to do with it. One of my boots is already ripped/missing. Maybe I drove over some brush and ripped it off?

Yeah, I've tried different zerks now and it makes no difference. I think the ball itself is blocking passageway for any grease to enter the boot. I think maybe I'll try a different brand next time.

Bumping this in case anyone else has experienced. I found some other threads that say sometimes they forget to drill through to the ball at the factory and suggested sticking a drill bit up inside.. Which seems crazy to me. I'm thinking about taking them back off and inspecting.

Live with them some time and then try to add grease again.

I had one tie rod end with similar problem, no grease will go in after installing. Tried like 3 different grease guns from my friends. About 6 months later when I did an oil change I tried again to grease it, and it worked. Tie rod was ok for many years also after that. I sold the car after that so I dont know how long it finally lasted.

You say this under the assumption that I have enough patience to quiet my brain's incessant worries about a dry ball joint. But I'll try

I do actually have these poly grease boots that I forgot to put on. Maybe if they're still giving me trouble in a few months I'll do a swap and take a closer look then.

Tried to grease the problem joint today. Still can't get grease in there. This is the driver side tie rod end.

Very simple,pull.the zerk,stick a pick in the hole and check to see if there is any dried grease in there.

As for guys finding undersized fittings,they are metric zerks.

As for properly greasing a joint,I'll let you guys figure it out

I know one of my boot is leaking because it ruptured. They're original to my Jeep, and so are the tie rods. I have 174,000 miles. Does anyone know how much it'd be to have a shop replace the tie rods? I have some sounds coming from that area so I'm thinking it needs to be done.

I popped off two of my joints last weekend and inspected. They're pre-greased so at least they're not dry. Still can't get any new grease in them. I replaced the boots with some ES poly boots I had and reassembled. I guess I'll try again later.

Just a thought. Next time you have them off take them to your local garage. Have them try and grease with their (hopefully) high pressure greasing machine. Can't hurt.
