Honda Inner CV Joint Grease.

[zmelli]

Time to replace a split CV Boot. The OEM Honda Boot Kits come with a yellow grease for the Inner Boot. I am thinking about getting some non-Honda boots from amazon Japan (Seiken Brand). The Boots do not come with grease. Honda sells Grease for the Outer Joint but not the Inner Joint. What is a proper aftermarket Grease for the Inner?

I asked chatgbt, this was the response: Do you think this was a correct response?

You said:​

Substitute for OEM Honda Inner CV Axle Grease Part number U131-15

ChatGPT said:​

For the Honda Inner CV axle grease with part number U131-15, you can use high-quality alternatives that meet or exceed OEM specifications. Here are some suitable substitutes:

1.​

• Look for grease that contains at least 3% molybdenum disulfide. This is commonly recommended for CV joints.
• Examples:
  • Valvoline Moly-Fortified Gray Full Synthetic Grease
  • Lucas Oil X-Tra Heavy Duty Grease

2.​

• Honda also uses Dow Corning or Shin-Etsu greases in various applications. Look for CV-specific products from these brands.

3.​

• Any high-pressure grease specifically labeled for constant velocity (CV) joints.
• Examples:
  • Red Line CV-2 Grease
  • Mobil 1 Synthetic Grease

4.​

• Many aftermarket CV joint rebuild kits include compatible grease packets that can also be purchased separately. Brands like GKN or TrakMotive offer these.

When replacing the grease, ensure:

• The grease matches NLGI #2 grade specifications for the application.
• The amount and compatibility are appropriate for your vehicle's requirements. Over or under-lubricating the joint can lead to premature wear.

If you're unsure, a local Honda dealer or a trusted auto parts supplier can confirm the compatibility of your chosen substitute.

It looks like the inner joint needs Tripode grease. The stuff is too expensive!

Anyone heard of this non-moly grease for inner Joint?

I run this Lucus in the desert car. The CV’s are ported and polished to add travel. We add 10% Bell-Ray amtiseize to it when they are new and refill inside the boot with grease after every few runs. I have never seen a failure after switching to this. Comes highly recommended by my CV builder. Bob Finders.

The rich race teams all use this and I probably will if I buy new CV’s.

NEO Synthetic, that's the oil I saw at the Toyota Grand Prix. Top Shelf for Race Cars!

That would be my pick. You need a soft, but not liquid grease without black MoS2. The needle bearings in the tripod joint need to roll, not slide. Black moly prevents roller/needle bearings from rolling. The factory grease, or so what NTN/J’TEKT uses is a Kyodo Yushi product, Raremax UBZ or something like that. I think it’s a polyurea-based grease. I have a OE Toyota boot kit in the garage with a 120g tube of each grease.

What toyota do you have that only has 120 grams of grease for the inner?

The inner tulip needs be flooded with grease all the time

Prius. Corollas and Yarii also call similar amount. The boot kit I got for a Sienna came with three packets of each grease in 60g portions. Toyota calls for 150-180g of grease for the inner and outer for that.
