To Do, or Not To Do.... (Timing chain)

I am once again having to dig into my cooling system. My radiator once again sprung a leak so I am replacing it and going to upgrade to a Hesco high flow water pump while I am at it. I also need to replace the power steering pump, as it frequently is cutting out. So while I have the front of the engine cleared out should I go ahead and replace the timing chain and gears? The engine has 132k on it has good compression, doesn't use any oil and it always looks clean and other than a surprising lack of power for a big 6, runs good. Thanks

Timing chain is pretty hardy on the 4.0, I've seen them go 300k plus.

Personally, I would skip it and save the money for gas, which is bankrupting us all!

Alright, thanks for the reply. Seems like that the info I am getting everywhere.
