Tips for removing rubber exhaust hoses and cast iron elbow - 2007 VP 5.0 GXi-G

[dhardest]

Hello, I'm about to start repair of a power steering actuator and am following the following post for guidance, which seems to be a very good step by step guide. However, I'm just getting started and having trouble getting the rubber exhaust hoses off along with the cast iron elbow. I removed the clamps of course but the rubber seems frozen in place, and tried putting some force to shake the cast iron back and forth to wiggle it loose but that thing hardly budges at all and it's hard to get in a good position to get leverage on it. Are there any tips and tricks to breaking the rubber loose? This is the step that in the post below it says is "easy"". Hopefully I'm missing something?

One thought that occurred to me is that it may be best to remove these by also removing the exhaust riser.

I had to do quite a few of these. But after you bumped it loose from the manifold, you can take a small flat screw driver and pry around the rubber to release it from the cast metal. Sometimes they tend to stick. I wonder if someone could have put adhesive on them also. Maybe a hot air blower would help to soften the rubber also. Dave-R

I also just last week repaired my steering actuator without removing the exhaust . I was working a a 23' boat and maybe had a little more clearance than you. I left one pin connected until I had the whole unit out. If the main pin is stuck, by swinging the drive hard to starboard, I was able to get a pry up on the pin from the gimbal housing. I used kroil spray to help loosen the pins, and could spin it with small visegrips. Once I got it out it was easy. I really wanted to meet the engineer who designed this for service down a dark alley with a tire iron. Good luck Dave-R

I did have some success loosening the cast iron elbow and almost had it out of the top rubber section, but there wasn't enough clearance to remove the elbow entirely. I think the best way to go is to remove the riser also, and then the rubber sections and elbow should come right out. The risers haven't been removed and inspected in a long time so probably good to do that anyway. But ran out of time since I had other things going on today so will pick back up next weekend. In the meantime some penetrating oil will hopefully do its magic on the riser bolts to make them easier to remove next weekend.

If you lossen the bottom clamps as well, then the boot should have more movement. I used a small screwdriver to break the seal.
IIt was much easier when I took the elbow and both boots off. Also if you grease the elbow the rubber boot will slide up over it once you get it free

Remove the riser, it is the quickest and easiest way. it is only 4 bolts and a small hose.

Mix some dish soap with water in a spray bottle. About 10% soap to 90% water. Work a screwdriver between the rubber and cast iron while spraying the soapy water in the gap between them. Keep at it until you've got all the rubber hose loose from all the cast iron and got some soapy water between them. After that the hose will slid much easier.

Hint: use the soapy water when reassembling.
