Pump rub?

[ecc_33]

How common is this "Pump Rub" I have had my truck since 35,000 miles and I know its only got a little over 49,000 now but everytime I change the ATF in the transfer case it looks BRAND NEW. I have changed it 4 times since owning the truck just for added insurance. Just wondered how common this really is?

Very common, ive seen it on truck below 100k miles too. I put one on my truck when it had 60k and it hadnt rubed through yet, but you could defenatly see where it had been.

Yikes...mines got 96,5xx probably should take a look see...probably should have done it when I did the trans lol

How much of a PITA is it?

I don't think the pump rub is directly related to oil change frequency. If the clip breaks, she rubs.

Now you got me worried too! Should check it out on my truck since I use the four wheel drive alot while plowing. Anyways, I see that Merchant Automomotive makes a DIY repair kit for $100.00. Might have to look into it.

I don't think its related to how much you use 4WD either. I have the Kennedy Simple Kit ready to go in with the trans swap.

I didn't change the oil frequently to stop the pump rub. I changed it often to try and catch the metal flake look in the fluid so I new if I had a problem or not. When your drag racing and truck pulling with a truck your maintance schedule changes quite a bit My family has had at least 9 dmax's and none have failed to the pump rub. Thats why I asked. I guess I should have put, I changed it so many times to try and catch a problem before something bad happened .... Running over 110 mph in the quarter mile sometimes makes me nervous when you look at some of the parts on these trucks. lol

I guess I won't have to worry about this now cause I just ordered the MA pump rub kit I figured what the hell, Already got the fluid out of it. Might as well rip it apart. Gives me something to do anyways lol:rofl:

Defenatly cheap insurance after you price transfercases or parts.

The clip breaks and allows the pump to drop and rub a hole in the back half of the case. Then either aluminum weld it or replace the back half. Or put the pump rub kit in for insurance.

Jb weld fixed the hole in mine..... Not sure, don't think it was 100 bucks though

The plate I got from mike was around 30 iirc

this clip your talking about is it a clip that holds the main pump in the trans?or does the whole thing shift backwards to rub on the transfercase? i just had to change my t case because there was no fluid in it could this be the problem? i never saw any fluid leaking and it was check last spring and changed

 

[ImpalaMax]

Nope nothing to do with tranny this clip is in the back half of t-case. Google t-case pump rub there was a good write up with pics on DF I believe.

True. My Lilly retired before her true potential came out.

Just pray dreaded red never sees the track or you will have the second fastest ECLB at the track. :spit: Either way we can :beer afterwards.

We have never run a t-case brace on any truck and have never changed fluid in one. My 05 has 135k on it and it's still alive and well, as are our 3 Dmax shop trucks at work with 120k, 208k, and 215k. I just jinxed one of them, hopefully a company truck and not mine.
