Rotton chassis repair

    Got a phone call off a local mechanic who had just failed the MOT test on a Mitsubishi Shogun due to the chassis looking like a colander. The owner has a boat and through years of backing into the sea, rivers and lakes etc.... it had taken its toll and i had yet another exciting day spent crouched under the wheel arch of some one elses pride and joy :welder:

    At first i thought it was a case of patching a few holes from just behind the rear wheel arch up to just in front of the rear wheel arch on both the near side and off side but once i had cleaned the rust away the n/s chassis leg had one continous hole about two and half feet long :doh:

    One thing i had on my side was the fact that this wasnt a p**s thin car chassis and the clean/good bits of the chassis were solid and i knew i had a good foundation to weld to.

    After cutting a few templates from card and transfering them to steel i managed to repair the chassis with full runs instead of having to stitch it here and there. A few of the original holes were covered up but apparently it doesnt matter and it will still still pass, which it did!!!:D

    Well done on the mot pass, it looks as though that chassis is on its last legs
    Out of curiosity and if its not too cheeky how much would a job like that cost the punter. I often wonder how much my diy efforts save me

    Great work

    Cheers chris

    Shoguns and Pajeros always rot at that point on the chassis after about 15-20 years, especially if they drive in and out of the sea. :) Water and salt get inside the chassis members and slowly rots it from the inside out. My Pajero's chassis is solid there thankfully. It's the thin (though not structural) floorpan that's rusting where it's taken a few knocks from rocks and boulders :)

    Good repair - like you say, those chassis members are pretty substantial steelwork, so you don't have to go too far back to find something solid.

    Shogun Chassis Repair

    Hi F.J.

    Following on from your thread...

    I'm new on here and have spent the last few days surfing the net looking for advice and help on repairing a Shogun chassis.

    I have a 1998 SWB Shogun 2800 GLS. Its been in the family from new and has been a great car. It has just over 80,000 on the clock and passed its MoT in April but the MoT guy scared me to death with: "You'd better sell it before the next test as the chassis is on it's way out". He also mark on the pass sheet; "Chassis starting to rot".

    I'd really like to keep the car as it's a useful item and would like to get it sorted sooner rather than later.

    I'm only in Oldham and wonder if you could also give me a quote? and as you like 'cash deals' I could bring it to you if that's ok.

    Please let me know either way if you or someone you know could help.

    Thanks in anticipation. Ian

    Hi Ian, if you could post some images up I could have a better idea of what I'm up against. I've had jobs before where the mechanic has all but written a vehicle off because of its rust patches only for them to be, I wouldn't say superficial, but a lot less worrying than first thought. If its the chassis then I can imagine that there will be good steel not too far from the damage.

    As for doing the job I dont have a problem fitting it in, I'm sure we can sort something out

    Look forward to the pics.

    Shogun Chassis Repair

    Hi Dean,

    Thanks for the quick reply.

    I'm away with work until the 16th. so when I get back I'll sort some photos out.

    I've not seen the rust myself I was just told what the MOT tester and mechanic said. Do you have a contact number you can PM me?

    Thanks again.

    Ian

    My SWB Shogun is very similar to the one you did here, there is nobody here good enough to do this sort of thing (I am only learning) would you consider another one if I sent you some pics?

    Cheers,

    Neil.

    Chassis repair - plate thickness

    Hi FJ,

    Thinking about using an SJ Suzuki chassis as a base on which to build an 'off-roady thing'. Does one have to use the same plate thickness as the original chassis or is there a recommended guage/thickness?

    Thanks

    Generally if you are patching up for MOT or cosmetics is suppose you could get away with thinner stuff but i would prefer to stick with the same gauge. However if you are building an off roader and need to brace up the chassis in any way then by all means use thicker stuff but nothing over the top

    You should always use the same thickness.

    Thinner & its to weak thicker & it wont crumple like its supposed to.
