Hi all. Tried researching online. Found some answers, but curious of best case of action.

was just having all my shocks and coils redone. Just got my 99 a few months ago.

rear passenger looks like this



and he can’t get the bolt there and nervous he is gonna break it.

so my question is - best to just by a panel available and cut that out and have it welded on? What would the name of panel be? I just found rear quarter chassis etc. is this it? Is this it?

reinforce and scrape away rust?

any other advice I’d appreciate. Thanks.

 

It's certainly rusty but based on what I can see in the photo it still looks like there's plenty of good material. I wouldn't see how it would break by replacing the damper. The stress that part receives daily driving would've already done that if it was truly corroded to that point anyway.

Also no, that quarter piece starts a few inches rearward. Also the photo of that quarter chassis might look confusing because it's oriented upside down.

 

A metric ton of penetrating oil and a long wrench, There is no problem putting a bolt in there, the issue is being gentle getting the old one out so you do not strip the nut.

 

thanks. He is saying he’s tried heat etc everything.

what is my option if that bolt breaks and he can’t get. Or we can’t get. Do they sell a replacement part that I can install? Cut away old piece etc. weld new I guess. Not that I want to do that but…. Thnx.

 

Well you would be pulling the gas tank to do anything that section is welded to the frame. I am on the west coast so not as much rust, but what I did on a previous vehicle was a long wrench and a framing hammer.

Heat the nut end up up then hit with penetrating oil do that a few times.
Then when while warm put the wrench on the bolt tap to tighten a few times, with luck you will get a bit of movement just a bit, then tap to loosen. More penetrating oil more tapping it took a couple of hours and much swearing bit it came out.
The possibility is bolt is corroded to the shock bushing, you can try twisting the shock to see of that is the case, if it will not rotate that is most likely the problem.

 

They do sell that shock mount piece that welds to the frame if it comes to that. I would think that would be an extreme fix. Just looking at the head of the bolt, it does not look like anyone put too much effort into it. I would try a different shop, It does not look that bad. I think he did not want to mess with it. But I would hit it Kroll a couple times a day for a couple weeks and then give it a go. Depends on timing, if you need it done quickly, heat is a good option, also once it is good and hot soak it with a crayon, the wax seems to help. also, tryin tightening it slightly, sometimes that is is easier and allows the bolt to wiggle a bit, more penetrant and more back and forth.

Its thats the spring perch on the left side of the photo, I would be more concerned about that rust.

What does the rest of the subframe look like? from the photo, I would think there is some structural rust there. I replaced the back quarter of mine last year, actually a pretty easy job. I could do in an afternoon now. Easy weekend job if you take your time.

 

AeroKroil is the move. Soak the threads for three days, spray it each day. If that fails you could cut the Bolt on the other side of the shop from the head and pull most of it out, then he could drill out the remaining threads and Helicoil it. Or weld a new nut in that place instead of the whole shock mount
