I do not understand why this statement is constantly made? I have never had an issue with my FASS gelling driving 1000's of miles every winter in snow, slush and single digit to sub zero temperatures. I have (3) 2nd, (1) 3rd and (2) 4th gen's in the family all running FASS in these conditions without issue. Just my but everyone is entitled to their opinion.

^^^^Thats what I was thinking

@trreed

I think it's worth it. I replaced the wheel cylinders about 4 years ago and noticed a difference. The front brake upgrade was very noticeable.

I kept 2nd gen calipers. I also have the larger wheel cylinders in the rear.

This is the route I took. Easy and an excellent upgrade

Swapping out the input shaft isn't bad. My front driveshaft on my old 99' let go and cracked my t-case housing. I picked up a used 47RE and DLD for a deal and sold the trans as a core. I just rebuilt the case because you're in there that far anyway.

Most times when things get older the get incontinent

How is the condition of the transmission mount? Could it be deteriorating and allowing too much flex causing the yoke to bind against the bushing and flex the seal?

You're not the only one

@KATOOM I have been getting ready for this bushing replacement myself. I have been looking at the same bushing @NIsaacs listed.

this is what I use for mine

@Haggar I completely agree with you and couldn't have said it any better. If a truck has the CAD why wouldn't anyone want the option?

No autos in the family unfortunately. No spacer on the 4500's like the starters on the 5600's

I have used mine on several nv4500's and a couple 5600's.

I believe @dripley is right. It looks like the vacuum supply to the transfer case.

Here's the one I have. No complaints here.

I think it is too. I recently went through a similar situation on a 99' Durango where the pedal would bleed down. On the ABS unit you should have a couple plastic vent caps, pop them off with a screwdriver. You can use a straightened paper clip stick it in where the plastic cap came off one at a time and have someone press the brakes. If the paper clip moves the ABS is bypassing which lets the pedal bleed down. I had an extra ABS module from another Durango I swapped it with and it is good now.

Yes Sir

@JAG1 you might go deaf if you're near my leg

I was hauling my uncles 99' on the gooseneck out of Silverthorne, CO heading up the pass when one of mine popped off and yeah it scared the c-wrap out of us!

I'm pretty sure it was @kzimmer that made his own
