What brand u-joints do you guys recomend? I think Im gonna swap out the ones in my rear driveshaft.

 

I go with cheap because you can grease them. The so called good 1s you cant. Just something about not greasing I dont like.

 

I hear good things about Spicer. I've never changed mine, but read several threads recommending them. I've been thinking about doing this, but mine are fine so I think I'll wait until I do my lift, assuming they hold out that long

 

If you mud then you want greaseable joints. Youll be glad you did.

 

Anyone prefer a certain brand? If the jeep doesn't see much mud is there an advantage to greaseable u-joint? I looked up the spicers and they seem pricey.

 

All depends on what brand you buy, You should always replace with greasable joints when ever they are available. NAPA has a decent replacement and it is greasable

 

Quick question about greasable, mine is mainly DD and will be my beach crawling machine eventually....should I switch to greasable too?

 

i will only run spicer these days.....broke to many auto parts store brands.

also if you have a greasable u-joint, the hole for the grease zerk becomes your weak point. i have broken every greasable u-joint i have ever put in.

i only run sealed u-joints because they dont have the hole and the u-joint is solid. i dont mind changing my u-joints due to lack of grease down the road rather than on the trail because i just wanted to grease my u-joints every time i go out.

go with sealed spicer u-joints!!!

ctm also makes bomb proof u-joints, but they are way over priced and you will break an axle or d-shaft before you break the u-joint.

 

Definately go with spicer. If you are running alloy front shafts.. I would upgrade to the cold forge spicer , but be careful about how much you upgrade your u-joints.. cause you move your weak link around. Personally I like to have my driveshafts be the weak link, cause breaking front shaft joints, or ring gears sucks.

 

nothing but spicer here. i price one for my superduty, and the cheapest was spicer,compared to a crappy made neapco from napa
