So I found a 261 HD near me that looks in good shape. Will this work? I’m not sure what the differences are between the 261 & 261 HD Sent from my iPhone using Tapatalk

I will check it out and report back. My dad bought this truck brand new and sold it to my grandparents a few years ago, so I know the case was never swapped out. I also am 100% sure it is a 2500HD. The plot thickens Sent from my iPhone using Tapatalk

Thanks for the reply, I actually arrived at that conclusion before seeing your response. After tearing it down completely, I see that it would take a very extensive rebuild to straighten it out. My relatives decided to put a cheap junk yard unit in and trade the truck in. Looks like I need the plain old NP 261. I’m surprised it doesn’t say HD, since it’s an “HD” truck Sent from my iPhone using Tapatalk

Hello, Yesterday I decided to install a pump rub kit on a relatives truck, an 07 Silverado 2500HD classic with the 6.0 & 4l80e. The transfer case is the NP 261. As I was working on it, I discovered the pump rub failure had already occurred, and the transfer case had been running with 0 fluid for an undetermined amount of time. Surprisingly, the bearings are not totally roached, but I think it would be a good idea to replace them. I’ll need a rear case half as well, it was worn through in 3 places. A quick search online revealed that there are tons of rebuild kits out there for these, I even saw one from Walmart which seemed odd. What is a good name rebuild kit to go with that won’t break the bank? Also, is it a good idea to put an entirely new pump in since it had been running with no fluid? And are any special tools required to do a full rebuild that I’m not aware of? Thanks Sent from my iPhone using Tapatalk

Thanks for the reply. I saw a pic of a newer bed on a pre 07 1500, but who knows what they did to make it fit. Oh well Sent from my iPhone using Tapatalk

Hello, just curious if anyone knows which year beds will interchange. I’m looking at putting a new take off bed on an 06 Silverado 2500HD, 8’ bed I know the beds changed in appearance over the years, and things like tail lights changed too. But what’s the newest bed I can buy that will bolt right up to the 06 frame? Thanks Sent from my iPhone using Tapatalk

I never figured it out, I sold the truck about a year ago to get a diesel. I never had any issues out of my Silverado trans despite the noise Sent from my iPhone using Tapatalk

Sounds like your trans is shot, time for a rebuild Sent from my iPhone using Tapatalk

Ok thank you. That’s what I was thinking too, just wanted confirmation before I start reassembly Sent from my iPhone using Tapatalk

Here’s the intake lobe for cylinder #4. All other lobes and journals looked fine Would you be concerned with debris from that messing up the bottom end? The truck ran smooth, no knocking whatsoever. The lifter was marked up but did not come apart, no needle bearings escaped Sent from my iPhone using Tapatalk

Thanks for your reply, that’s good to know. Looks like I will go ahead with a new cam and 16 new lifters Sent from my iPhone using Tapatalk

What do you guys think of this cam bearing? They all seem to be about the same. I really do not want to have to pull the engine all the way apart and send it to a machine shop to replace them My buddy said when he rebuilt one of these that the bearings were all showing some brass. He didn’t replace them and it’s been fine. Thoughts? Sent from my iPhone using Tapatalk

Ok thanks for the replies. I guess I will just get a stock replacement because I don’t want to mess with tuning at all Sent from my iPhone using Tapatalk

I am replacing the camshaft and lifters on a 2007 Silverado 2500HD with the LQ4 6.0 engine due to a slightly chewed up lifter. Who makes the best mild performance cam for these engines? I do not want to do upgraded valve springs or pushrods or change the tuning in any way. The truck is only used to pull a 1 horse trailer, not looking for anything crazy Suggestions?

I will say, I do miss how fast a gas engine warms up. That’s about the only thing I miss. I used to have an 01 Silverado with the 6.0 and a 97 jetta with a 2.0 gas engine. I have since upgraded to an 00 7.3 powerstroke and 99 jetta TDI. Overall I am very happy with my diesels, my tdi is yielding almost double the mpg that my 2.0 did. (25 vs 45-50) gas engines are definitely better for short trips. I feel bad starting up my diesels in the dead of winter and putting all that wear and tear on them just going to the store or something or something short. To each his own. Glad it worked out for you[emoji106][emoji2534] Sent from my iPhone using Tapatalk
