why couldnt GM put a drain plug on the differential?

[nikon]

sorry just had to b*tch...Im at work, and its dead so I decide to change my rear-end gear oil.....of course you gotta rip the cover off to get the oil out :mad: luckily I AM at work so I just picked up a new gasket even though I couldda reused the old one...total cost...bout 6$....they got the oil here where I work :D ...I love working at a dealership...now I have access to a lift whenever I want for free :D ...anyone wanting to do this...I recommend doing it on a lift...I would never have gotten it done if I was using a jack...

Because GM is cheap I guess.

its not too bad w/o a lift...once you get the routine its not bad...

Adds too much to the manufacturing cost of the cover. No significant benefit for the added cost.

the lack of the drain plug doesn't bother me

now adding diffy fluid, THAT bothers me -- if you ask me adding the new fluid is the b*tch of that job.

Replace the stock cover with a t/a girdle and stud kit.
It has a drain plug [img]smile.gif[/img]

you only need to change the rear diff fluid every 2-3 years (24,000-36,000 miles). that doesnt rate a drain plug. same applies to the transmission pan (and its far messier due to amount of fluid involved)

you are actually SUPPOSED to change it more often than that, i think 7500 miles, but not many do that. it's a messy job either way you do it, but i agree, filling it is the toughest part.

According to the GM Service Manual for my 96, the differential fluid is to be changed after the first 7500 miles, then monitored and topped off as needed thereafter.

Changing it at 7500 is an excellent thing to do... on a street car every 15,000 or every 30,000 miles from then on is a good amt of time. I do mine every 15K [img]smile.gif[/img]

I work at a quick lube type place and we had a small sucker that we used to do the job. I did mine in 10 mins or so and it's not that messy. The sucker connects to an air line and has a "straw-type" adapter and you just put it down the filler hole. The suckers aren't that expensive either. Thought ya might wanna know!

Yea, I heard about those. I totally agree with what strobhen said. Taking it out and cleaning it is no prob. its ADDING it that takes me forever. :mad: oh well! [img]smile.gif[/img]
