Check Your U-Joints

Although that may be true you don't want Molly I'm everything. Molly works well in high pressure friction areas where the Molly gets crushed and creates a lubricated surface. Seems like a lot of things can benefit from this but the problem is that if the metal parts are not hard enough the Molly will pit the bearings and being race/sleeve. I believe the rule of thumb is Molly inn slip yoke and non Molly in Unoints.

 

yes they actually stopped making the #2 Heavy Duty MOLY grease and have some other ,but I used it when they had it and also the Unversal Multipurpose #2 Synthetic both worked fine for me just grease on regular basis alls good, now I use Redline CV2 MOLY which I really like best of all

 

basically 200,000 miles of using AMSOIL Heavy Duty #2 MOLY in all my joints in an 2004 GEN1 with 0 issues as far as the joints=WINNING http://www.syntheticoilonline.com/amsoil_synthetic_grease/synthetic_heavy-duty_grease_nlgi_2.php

 

I have a 2WD 2013 Prerunner Access Cab 2.7 and I definitely have the grease fittings.

 

nice camera.

 

On my Isuzu I got close to 170k on the original u joints using non Molly before the engine have up. I'm going to say greasing the u joints regularly vs not doing it will probably have a larger impact than what grease you use. The information I provided is technical info for OCD people such as my self. I can however say that the hub bearings developed pitting on new bearings and race after 5 years. Seems like things like differential oil and u joint maintenance are one of those things that are over looked but your average Joe.

 

well im just saying from my experience using AMSOIL MOLY fortified grease for over 200k miles on my truck with 0 issues using it seems for me that alls well in U joint world the truck was a 2004 got rid of it with 256k miles on it no race bearing issues that I know of.

 

Those u-joint pictures were taken with my iPhone 5. I'm in Florida so there's no snow/salt roads eating up the undercarriage. It's got some wear with 37K miles but it's still in great shape. I don't off road much. Occasionally I'll get on rougher dirt or sandy roads for mountain biking or kayaking spots but mostly city/highway driving.

 

Moly shouldn't be a problem.

 

Are you sure those weren't install after sale? They seem WAAAY too accessible for from the factory.

 

They look just like the factory ones on the 2016 Tacoma. The grease fittings for the front shaft aren't as accessible as they fill grease into the cross instead of into one of the cap ends.

None of the 2005-2016's have double cardan joints, they're all single u-joints. Toyota doesn't spec moly grease for any of them.

Having read this thread, and since the weather is unseasonably warm here in northern IL, I went under my truck with a 10mm socket and my grease gun loaded with a fresh tube of lithium-base.

(3) of the (5) zerks took about 10 pumps of my small, one-hand gun before grease started to push out of the seal. (2) of the (5) zerks took about 5 pumps before showing grease.

Interestingly, the grease that first appeared at the seals was NOT the same colour as the grease that I was using. This supports the Toyota procedure of greasing the U-Joints BEFORE assembly, as suggested by Mr. Jeff Lange.

I do have a couple questions for those more experienced than I. (4) of the (5) zerks, although brand new and clean, did NOT seal after I pulled the grease gun fitting off of the zerk. They allowed the grease to escape past the check valve, squirting it out in a thin stream.

Is this normal? Is it a problem?

Thanks.................. Frank

 

I stand corrected, I had always heard the 2WD didn't have them. I guess it changed at some point. Better to have them IMHO.

 

That is a topic I wished to avoid in this thread.

 

Any grease is better than no grease.

 

yes but 256k miles with a MOLY grease and the World kept on turning and so did the U joints

 

That's great

 

I think moly vs non-moly in the u-joints could turn into a thread that could rival an oil thread. I use an extreme pressure para-synthetic grease with moly. IMO there is a lot of conflicting evidence that says moly can "build up" in ujoints, but some say (including Shaeffers) that's not true and it acts as a back-up lubricant if a joint gets washed out. Almost as a dry lubricant still protecting. Then there's the brass thing....I will say that I have run several aftermarket driveshafts over the years and the last two manufacterurs recommended #238. They both recommend using it in the slip, DC and u-joints. Some say run moly in the DC joint and lithium in the u-joint but a double cardan is basically 2 u-joints so......either way it's a topic with lots of opinions.

 

Calcium sulfonate?
