  • WHY BUYING ARB 750003 DIFFERENTIAL COVER FOR DANA 40: When off-road, it is inevitable that obstacles and off-road hazards will be encountered that could potentially inflict expensive damage to your differential. To prevent this, ARB manufactures the Differential Cover. Using high tensile nodular iron, it has been engineered to protect the differential and ring and pinion set from any off-road hazards.
  • IMPORTANT ARB 750003 FEATURES: Computer-optimized cross brace design increases the structural rigidity of the axle / Top quality neodymium magnets / Prolonged carrier bearing life / Magnet location in the end of the dipstick
  • BEST ARB DIFFERENTIAL COVER OF ALL: Computer-optimized cross brace design increases the structural rigidity of the whole axle / Unique dipstick/filler cap design allows differential oil level to be adjusted for customized high driveline angles / Prolonged carrier bearing life due to extra support to the bearing alignment / Top-quality, high-power neodymium magnets are used in both the drain plug and the dipstick to collect metallic wear particles as the vehicle moves
  • ABOUT ARB 750001 COMPOSITION: Made from ‎Super Thick Cast Nodular Iron, the engineering of the cover will prolong carrier bearing life because of the added strength to the bearing alignment. The dipstick/filler cap allows the differential oil level to be adjusted.
  • HOW IT OPERATES: High-powered neodymium magnets are attached to the drain plug. The dipstick collects the metallic wear particles. The magnet's location on the end of the dipstick allows the oil to be checked

CUSTOMER REVIEW - AMAZON VERIFIED PURCHASE

"Construction is sturdy, definitely a piece of armor. The integrated dipstick and hole make maintenance and oil changes a breeze. Consider the lube locker gasket for quick maintenance jobs. Believe me, this thing works nice, looks nice, and is probably the best-constructed diff cover I've seen"

I'll be honest: Bought this to look cool under my Jeep; changing to synthetic diff oil was a bonus of the install. I'll never offroad enough to test their limit. Ended up buying the Dana 30 cover for the front after installing this. Very very high quality, and the red looks great. Dipstick makes it super easy to fill. Installed with Lubelocker gasket to make install much easier - hardest part was cleaning off the old gasket sealant.

This ARB Diff Cover went on my wife's 2013 rubicon stock i got all the bolts off fine except one the long top left side.. the track bar or sway bar was in the way couldn't get it on i tighten all them added lucas synthetic gear oil (about 2 and 1/2 ) L., and drove in reverse up the sidewalk to clear the last bolt, i suppose you can use a lift or jack to lift out of the way but i found it EZ-er to just drive the rear tire up on the side walk to create some flex enough to clear, other than that it took me no more than 30 min to install, paired the diff cover with a Lube Locker Gasket so no messy RTB. Looks great now the jeep needs another in the front to match! i recommend this to any 1 with a D44... ARB you guys Rock ! too bad no Decal in the box, i wish they included a sticker to put on my jeep like the lube locker that came with a decal....

It took all of about 30 mim. To take the old differential off and install the ARB cover. I will be purchasing the DANA 30 for the front end now. Make sure you purchase the lube locker gasket it makes the installation complete. Super fase and easy. For those of us that use our Jeep off road this is a must. Oh by the way it looks GREAT too.

Excellent Product. Fit right onto my 2002 TJ front axle with no issues, took 1.75 Qts of oil to properly fill. Looks great, and is much tougher then the original. I had to file down the mating surface on the diff. it has some dings and such. But 2 weeks later, not a drop of oil.

Construction is sturdy. Definitely a piece of armor. The integrated dip stick and 2nd hole makes maintenance and oil changes a breeze. Consider the lube locker gasket for quick maintenance jobs. ARB has definitely priced this like they are really proud of their product. Believe me, this thing works nice, looks nice and is probably the best constructed diff cover I've see for the D44. That said? is it worth paying twice the cost of an alternative aftermarket cover? I don't know, you can be the judge of that. Just know that if this does fit in your budget, you won't be dissatisfied. If it doesn't fit in your budget, get the alternative and your will probably be happy with it too. So, at the end of the day this is kind of the Louis Vuitton of diff covers.
