Re: Do I need new LCA bushings?
Well after watching some youtube videos on LCA bushing replacement I've spent most of the day getting myself psyched up to do this job. But I am not surprised many of you suggested to replace the LCAs altogether. I saw a lot of that on other threads, and certainly understand the rationale there. The tech did say that the bushings were cracked and deteriorated, so I know I need to do something, eventually. I'll try to snap a photo of them when it's dry outside.
I plan on keeping this truck basically forever. And I'm likely going to continue having fun with it and pushing it as hard as I can. I did see one or two reports where people had blown through multiple sets of LCA bushings and had to keep replacing the LCAs. I'm afraid given the way I drive I could fall into this category. It may make sense for me to get into a position where I can periodically replace these bushings on my own every 50k miles or whatever ends up being necessary. I'm also reading that the aftermarket poly bushings will provide better handling than the rubber bushings and have additives to keep them from squeaking. That sounds appealing to me.
Decision one way or the other isn't final, but hopefully some of you can comment on some of these questions/comments:
1. If purchasing new LCAs, and I'm interested in having poly bushings, perhaps I purchase aftermarket LCAs with them already installed? Any suggestions on which ones?
2. If the rubber bushings by default provide some "float" and a poly bushing doesn't (or provides less) when the LCA takes a hit is this energy no longer being appropriately damped by the rubber and being transferred elsewhere to another part that could then prematurely fail? aka. is there advantage to having the rubber bushings?
3. Does anyone have a suggestion on a good bushing press kit that could be used to do this job? If I'm going to do this a few times over the lifespan of the truck it's far cheaper to buy one than multiple sets of LCAs or anything else for that matter that requires a press.
4. I saw one thread suggesting drilling and tapping holes in the factory LCAs for zerk fittings. Seems like a good idea to keep the bushings lubricated - any thoughts on this?
5. Once I get poly bushings installed my assumption is that future replacement of these bushings would be easier (ie. no more propane torch to heat rubber, etc). Is this correct?
And lastly, just for reference, here is what my parts estimate was for having the LCAs replaced at the shop:
