Diff fluid change help

Just changed diff fluid bought this from Harbor Freight - don't know what it pumps but it didn't pump the diff oil. Any suggestions or links on what in your experience does work to speed up the process greatly appreciated.

 

I've always just used this. It's simple and handles 140 fluid just fine.

I've seen them sold at any auto store.

 

I use one of these

Cheap and easy... just stick it in the gear oil bottle and pump it into the fill port.

 

I purchased quart bottles of Mobil1 75-90 squeeze/poured it in both front and rear diffs.

 

I refill the diff the same way I refill the automatic transmission - from above.

Long stretch of large heater hose feed over top of right rear tire down into the diff fill hole area. Plastic tube that's connected to that end with hose clamp fed into the fill hole. Source that from HD/Lowes/etc. Connect funnel to other end of hose up above - pour in gear oil. Pumping from below - be it tranny/diff is a pain.

 

Looking for a fluid transfer pump to make this job easier....will come in handy for front dif/tc & rear diff as well any drain and refill of transmission. Any suggestions out there? what is everyone using?

 

Thanks guys for all your replies, information and help.

 

I did this the last time I changed my manual transmission fluid but I used some 1/2" polyethylene tubing I had left over from a whole house filter I put in. You can buy this at Lowe's too. It worked really well and I just used the squeeze bottles from the wheel well.

 

I drop the spare tire and pour the diff fluid right in the hole with the extra room created. Hit the spare tire with fluid film and crank her back up. Done!

 

This right here.... way easier to pour a quart at a time in that sit there jerking off a lil hand pump 4cc's at a time for 3 quarts.

 

Did you find one that does the job ??

 

I used this one. Chose it because it comes with an adapter for my Yamaha outboards. Worked great for pumping gear oil into my Tacoma diffs and tranny.

Use a hose and funnel and let gravity do the work.

 

Tried a hose and funnel and gravity - took for ever - maybe there is a technique to it but didn't work for me. Thanks.

 

Thanks for the link.

 

I'm going to try the Motive Transfer pump next time......will fit under the truck and can be used for both the Dif /TC and Transmission fluid change.

Thanks.

 

I have one of those, I suspect the diff fluid is too thick for that. You can use a 1 gallon pump sprayer, basically the same thing.

The motive is amazing for flushing brakes.
