Its time to fill up the rear axle with gear oil. Lets talk about different weights and types of fluid as well as different brands.
There is also a friction modifier you might need.

I just bought a two-gallon jug of SAE 80W-90 today. I also looked at some additives but I couldn't decide. Thanks for the tip on the friction mod product.

If your 80W90 has an API GL5 rating It already has an extreme pressure additive.. If you have a limited slip differential differential or some other rear axle with multiple disc clutches or one clutch it will require an additive suitable for for the type differential you have

I use Lucas, but then I wanna try some different so I switched to Amsoil 100% synthetic gear oil ran it for one year now and so far so good✌️

I put Amsoil in my 2014 F-150 with the 8.8 rear end. So far so good. Would use Redline or Royal Purple with confidence as well. Even the Supertech oil from Walmart would get the job done especially if you’re just daily driving but it’s nice to have that comfort of using a premium product.

Good choice with amsoil

Royal purple is overrated (and overpriced)

RP is way overrated and not that good . No better than the parts store on sale brand what ever that may be .Hard to beat amsoil or red line

Here's the short version for free. Use a brand name synthetic. Be ware of old pinion seals. use the correct weight. Use a "modifer additive" for clutches if u have them in the center section. This allows u to not worry about looking for the "LS" listing on the bottle(limmited slip).

Thanks for watching and commenting! I have never used Mystik I would say the most important thing is to use the recommended weight

I like Valvoline Conventional 80w90 no lsd additives.

@CindyinArizona 10 ай бұрын

Did you say if you're using a "sure grip" gear oil you need the additive? Could you clarify that. Also, just watched a test of gear oils and Lucas failed, didn't meet industry standards, neither did Mobil 1. Is that a 1970 Cuda? Sweet ride for sure.

@backyardhotrods9885 10 ай бұрын

Yes definitely need an additive. I’m using a Ford one Dr. Diff sells. Wow surprised to hear Lucas didn’t test well.

How do you drain the old gear oil?

@backyardhotrods9885 3 ай бұрын

most rear axles you need to unbolt and remove the center section to get the old oil out. I drilled and tapped my mopar 8.75 rear axle and installed a small drain plug to make it easier to service

Yeah, they are done. I remade the cardboard checklist and didn't cross it off yet for this video lol

Non Synthetic is the stinky version. Old Synthetic won't smell as much. Its the additive you're smelling to diminish GL5 from GL4. Nothing about how old it is. If it's 90w GL4 it won't smell like GL5 90w . Cannot swap them around. They're separate purposes. GL4 for 3 speed transmission etc 4 whatever and GL5 for the axle only whether its a sedan coupe pickup or full floating pusher axle on a transport tractor. The clear window cups to oil the outside axle bearings
