Best Cv Joint Grease (2026): 4 Picks by Base and Size

Compared on paper

Specifications are manufacturer rated, collected 28 October 2026. Where a listing contradicts itself, both figures are shown.

How the points were given

Each grease is scored on performance, build, value, safety listing and warranty, using only what the listing publishes. No listing here states a safety certification, so safety scores zero across the group, while only the Dorman 614-066 listing states a warranty term, a Limited Lifetime Warranty, and scores there. The ranking otherwise comes from base, pack size, stated temperature range and viscosity grade.

Scores run from 9.2 to 9.8: each product’s point total is placed on that range, so more points always means a higher score.

What the listings tell you

Pack size splits this group more than base does. The Dorman 614-066 pouch holds 3 oz and is stated as the right amount for servicing one joint, the Sta-Lube tube holds 4 oz, the Dorman 03618 holds 1.6 oz, and the Red Line cartridge holds 14 oz. Bases split three ways: lithium on the Sta-Lube and the Dorman 03618, molybdenum disulfide on the Dorman 614-066, and synthetic on the Red Line, with the Sta-Lube adding polymers and the Red Line adding red moly. Viscosity grades are stated on two listings only, 10W-30 on the Sta-Lube and 0W-40 on the Red Line, while neither Dorman listing states a grade. A temperature range is stated on one listing only, the Red Line at -100°F to 500°F, while the Dorman pouch states highly heat resistant lubrication with no figure. Warranty terms are stated on one listing only, the Limited Lifetime Warranty on the Dorman 614-066; the other three listings state a limited or manufacturer warranty with no term.

Buying guide: best cv joint grease

Moly content first

Three listings here name molybdenum in some form. The Sta-Lube grease is lithium-based and fortified with molybdenum disulfide and polymers, and the listing states it is designed to survive the stress and shock loads encountered in CV joints. The Dorman 614-066 lists molybdenum disulfide as its material and states long-lasting lubrication that is highly heat resistant. The Red Line cartridge is a synthetic grease with red moly, stated for wheel bearings, U-joints and high-angle CV joints. The Dorman 03618 lists lithium as its material with no moly stated, so a reader who wants moly in the grease should pick from the other three listings. Moly content is not the whole story, since the Red Line listing also leans on its synthetic base and its stated resistance to oxidation and corrosion, but it is the clearest split in this group.

Size and pack second

Match the pack to the job in hand. The Dorman 614-066 pouch is stated as just the right amount for servicing one joint, which makes it the simplest pick for a single boot job, and the listing also states the pouch is included with Dorman’s CV Joint Boot Kit. The Sta-Lube tube at 4 oz and the Dorman 03618 at 1.6 oz are small packs for one joint at a time, while the Red Line cartridge at 14 oz is the pack for a reader who services joints often and wants one cartridge to cover several jobs. A pouch suits a single Saturday job with nothing left over to store, while a cartridge suits a home garage that sees regular driveline work. Check the stated size before ordering, since the Dorman 614-066 spec table also lists a liquid volume of 90 ml beside the 3 oz pouch size, and the Sta-Lube and Dorman 03618 listings both state 0.12 liters beside their ounce sizes.

Viscosity grades third

Two listings state an SAE J300 viscosity grade and two do not, which matters when the vehicle manual calls for a grade. The Sta-Lube states 10W-30 with a base oil viscosity of 68, and the Red Line states 0W-40, so a reader whose manual names one of those grades has a direct match here. Neither Dorman listing states a viscosity grade, so a reader who needs a stated grade should pick from the Sta-Lube or the Red Line. The Dorman 614-066 listing instead leans on its stated heat resistance and its lifetime warranty, and the Dorman 03618 listing gives package dimensions and weight rather than performance figures. Grade is one check among several: base, moly content and pack size still decide most of the choice, but a missing grade is a real gap when the manual is specific.

Temperature and use fourth

Only the Red Line listing states a temperature range, from -100°F to 500°F, with stated resistance to oxidation and corrosion, low evaporation and oil separation, and a minimum effect on rubber seals. That range is the reason to pick the Red Line for work that sees extreme heat or cold, since no other listing here gives a figure to compare against it. The Dorman 614-066 listing states highly heat resistant lubrication and lists recommended uses across wheel bearings, ball joints, U-joints, hinged parts, cables and chassis parts, which makes it the broadest general automotive pick here. The Sta-Lube listing stays narrow, stating CV joint installation and maintenance for domestic and import joints, plus CV boot and front wheel drive passenger vehicle use. For bearing work beyond CV joints, see the best grease for bearings guide, and match the stated uses to the job rather than assuming one grease covers every driveline part.

Garage Fit Check

• Check the pack against the job: a 3 oz pouch is stated for one joint, while the 14 oz cartridge covers more work.
• Check the base: lithium, molybdenum disulfide or synthetic, against the joint in hand.
• Check the viscosity grade where stated: 10W-30 on the Sta-Lube and 0W-40 on the Red Line, with no grade stated on the Dorman listings.
• Check the warranty line before ordering: only the Dorman 614-066 listing states a term, a Limited Lifetime Warranty.

FAQ: garage tools

What grease suits a CV joint?

The listings here point to moly-fortified lithium grease, molybdenum disulfide grease and synthetic grease with red moly, all stated for CV joint installation and maintenance. The Sta-Lube and Dorman 614-066 listings name CV joints directly, and the Red Line listing names high-angle CV joints among its uses. Match the base and any viscosity grade the vehicle manual calls for.

Do bearings need grease?

The listings here state greases for bearings as part of their uses: the Red Line listing names wheel bearings, and the Dorman 614-066 listing names wheel bearings among its recommended uses. Grease is part of bearing maintenance in these listings, and the pack sizes here run from a single-joint pouch to a cartridge for repeated work.

Do you need to put grease on wheel bearings?

The listings state wheel bearing use for two greases here, the Red Line synthetic and the Dorman 614-066 molybdenum disulfide grease. Whether a given bearing needs fresh grease depends on the job and the vehicle manual, which no listing here replaces. The listings state the greases, not the procedure.

How do you grease a bearing?

No listing here states a greasing procedure, so this guide states none. The listings state the greases and their uses, such as CV joint installation and maintenance, and the vehicle manual covers the procedure for the bearing in hand.

How do you clean wheel bearings?

No listing here states cleaning steps, so this guide states none. Check the vehicle manual for the cleaning procedure, and check the grease listing for the base and size that suit the job once the bearing is clean.
