How to remove the stock dump pipe

[fridayman Senior Member Find all posts View Profile Close fridayman]

I had my truck into a local exhaust place to fit my Beaudesert dump pipe, but they said that they could not get one of the stock dump pipe nuts off (the gearbox is in the way). Is this correct? And how do I get the stock dump pipe off without moving the gearbox? Can I take the turbo off with the dump pipe and just bolt it straight back again with the new dump pipe fitted?

fridayman you not at the same garage that was doing / not doing your wheel alignment are you , lol . Having worked on cars ect in Pommie land (salt on the roads rusted seized bolts) I would say they don't want to do the job for fear of snapping bolts in the turbo and having to replace it .

LOL I'm not sure if it is just me... but it feels like you can't find anyone over here that can do a job properly - I'm not saying I don't make mistakes, but I'm not taking people's hard earned and I'm usually happy to have a go at most things. This is part of the reason I am moving to Oz. You guys have it good with all the aftermarket suppliers and garages that are familiar with Toyotas. Its all about Land Rovers over here.

I might take it Toyota to fit the new dump pipe and then go back to the exhaust place to make the adaptor for my 2.5" system.

Did mine years ago when I changed the exhaust on my old Prado. I am surprised an exhaust shop had issues with it.

There was a great article on here years ago that covered but I cant find anymore, the link was www.pradopoint.com/viewtopic.php?t=3040 Maybe someone can find it.

To remove the nut you are talking about, you have to remove the front wheel, remove the rubber shield so you can see the dump pipe, spray heaps of WD40 or similar and let it soak for as long as possible. Use a 1/4" drive ratchet with a short extension and 12mm (from memory) socket and reach around the back of the dump pipe to access it. It was an absolute pain to remove. If you stuff the nut, you are removing the entire turbo and manifold to get at it.

It took me a while to get that nut off, skinning knuckles and swearing is part of the process.

Hope this helps

DWG is right, take your time and they are very tight. make sure of a good socket fit. Did mine years ago also, putting the new one on was easy because buy then you will have worked out what sockets and little short spanners you will need. Good idea to put an extra mount from gear box to engine pipe before flex. may stop dump pipe cracking.

Thanks guys. I have ordered some 6 sided 1/4" shallow drive sockets and some wobble extensions - hopefully I can get it off myself. I have a bad feeling that the exhaust place have rounded the nut though - they mentioned something about it being rounded...

Several knuckles bled and there was lots of cursing, but I can't get the rear £%^$... err nut... loose. I was barely able to get my socket off again. I will have another go this weekend. The good news is that it is definitely not rounded.

Heat and cool, heat and cool, wd40 and patience. This is one mother of a job. I think there are pics and a write up in my rig build. It took my mate 2 days to remove the last bolt but he got it! ABSOLUTE SHIT OF A JOB is the politest way to describe it. For the record, the nuts are NOT round, they are oblong and basically not designed to come off easily, add rust, seizing and exhaust temperatures of around 500 degrees and you understand why this is a biatch of a job.
