T-case shifter rattle

[MtnHaul]

Since I've owned my truck the t-case shifter starts to rattle/hum at about 2400-2500 RPMs and I have read the recall/TSB notice regarding this issue. From what I have read the "official" fix was a new shifter but that seems excessive. I found one fix here where a member suggested slightly prying on the mechanism from under the vehicle until a small pin no longer makes contact with the t-case housing. Sounds easy but I tend to be cautious when it comes to "use a bigger hammer" type fixes. What fixes have you guys had success with? The rattle gets annoying and I'm worried I'll blow my speakers if I turn 'em up any louder!! Thanks in advance.

putting a grease fitting and pumping the shifter assy full of grease, makes a big difference in this. Also keeps it from getting stuck..they are well known for that.

You could also have some worn injectors, throwing the engine balance off.

Was that member me? If not,I did this also and it cured all that ailed her.It took me a few times looking to figure out just where that rattle was being made.Once I saw the issue,the fix took just a few seconds.Don't worry,a little prying isn't going to break it.

i unbolt the shifter and remove the stupid plate behind it. this way no need to push over or down(depending on your year) to get into low

Yep F250HDXLT, when I searched on this issue here your post was about the only useful thing I found. Great idea too Dieselcrawler--kinda' don't like having to push down to get into 4-Lo, especially since I actually use it as 2-Lo all the time. Hopefully this weekend I'll get it sorted out, thanks for the replies.
