New Rockcrusher Diff Cover

You run 10 bolt axles. :haha:

That he bought super high strength covers for his 10 bolt?

Just kidding, no idea. Whats the problem?

Covers look good, although most guys here go towards steel plate covers.
 
Funny guys

There is no fill hole or plug. I just called Rockcrusher, they said "Oh yeah we noticed that too, we're machining them now, so we'll have to send you a replacement". How do you not notice this when you build them all the time/
 
That looks like a 10 bolt rear cover, dont they have the fill plug on the side of the diff? I know 10 bolt fronts fill from the cover.
 
Front Diff

Yeah it's a front cover, that's what they offer and that's what I ordered. It seems like they goofed somehow. What sucks is that I've been trying to get one since Feb. There's no love for the bastard Chevy 10 bolt.
 
Man, thats no problem.

Especially if you have a winch. Just do like I used to down in the swamp when I needed to change a U-Joint on my Jeep.

It was too muddy to crawl under, so I would throw a rope over the nearest live oak limb, use the rope to pull my winch cable over and then use the winch to pull the Jeep up until the U-Joint was at an easy height.

Just get the truck vertical enough with a winch, or a really steep hill, pour in the oil, bolt on the cover and let it all back down.

For a diff that would be practically vertical, nothing I would want to be under :rolleyes:

Pour it in through the breather, drill/tap your own hole or wait for them to send you another.
 
On a hill might be tricky, but hanging from a winch cable, you are actually standing beside it, not under it.
I never worried about the Jeep falling, if it did, it would land on its tailgate, and would balance there long enough for me to step aside.

I did watch that limb though.

still nothing

So I've emailed twice and got no answer. I called and they once again said "It should ship this week". That's the same **** they've said back in Feb when I tried to order one then. F*ckin Rockcrusher has the totally worse customer service ever! I'm gonna wait until next week and then put a stop payment in.
 
Update

Today, I was on vacation so I decided to tackle what should have been a easy install. My brand new (with fresh paint) RC diff cover. After the previously mentioned problems and hassles this should be easy. I've been losing interest in my K5 and off roading so I thought this would help re-spark my interest.
I removed the OEM cover, cleaned the surface of the 10 bolt and got the RC cover ready. I applied the black silicone, and got the cover in place.
THE FIRST PROBLEM: As I screwed in the supplied hex bolts I noticed they were alittle smaller than the stock ones. So much so that there was only two twists to seat them in, they really did not seem secure. I continued to install the bolts.
THE SECOND PROBLEM: I got to the last bolt and it seemed that it would not line up. I adjusted the cover, loosened the screws( only two twists to tighten) but it would not line up. I finally took a piece of rod and tried to "FIND THE HOLE". As it turned out, one cover bolt hole is OFF! No matter what I did one of the cover bolt holes was off. WTF!
So I installed the bolts (except the off set one), all the other bolts fit very loose.
THE THIRD PROBLEM: The supplied hardware is too short, once all (except the off set one) bolts were installed the cover was not really tight. I decided to use the OEM hex bolts instead. Once installed the cover fit nice (with the missing upper bolt).
I continued, I waited two hours for the silicone to sure and unscrewed the filler plug.
THE FOURTH PROBLEM: once I filled the carrier with fresh gear oil I tried to screw the filler plug back in. For some reason the plug would not seat, it would turn one turn and slip back out. That's when I noticed loose bits of steel. On closer inspection it seemed that the threads in the plug hole were stripped! WTF! I only removed the fill plug once! FU*KING RC sold me one big POS! The plug would not seat, the tapped hole had stripped threads. I tried the OEM plug and the would only seat two complete turns. So now I have to contact RC and see just what those jack*sses are going to do! What a complete waste of time.

FYI don't give me sh*t about using 10 bolts, I only off road maybe twice a year so a major investment of 1 tons, with new tires and wheels is completely out of my budget!

the hole is just stipped, look at the metal shaving coming off it in the last picture. Find a big enough tap and chase the threads.
 
I just emailed RC, I sent the pics and pretty much what I wrote here. Now I'll see what they say. I'll keep you posted.

Hopefully they get you a new cover, and refund part of your purchase price.

Even better reason to buy from the "small" guys on here.
 
That particular cover is for a REAR 10b. Notice the bolt pattern is round. The FRONT 10b has one offset bolt in the 1 o'clock position (see and compare the pics of cover/axle). That cover should fit your rear 10b once you get the fill plug issue fixed.

Which leads me to ask, what are they doing over there? Putting fill plugs in covers that don't need them and no fill plugs on covers that do?! It's an easy fix but that doesn't make it a front cover.
