the last thing to mod at the rear end is to mount the exhaust silencer on rubber mounts to stop it rattling cos it was previously bolted solidly to the chassis beam which made it rattle
I marked in white where the exhaust CoG is to locate one of the mounts to keep it balanced
I wasn't a fan of the traditional exhaust rubber hangers cos they're too floppy and move too much.
Decided to get these solid bolt-on Bobbin-type rubber mounts in halfords, meant for rover mini's.
some ppl use them to support the exhaust under shearing or tension load but that'll stress & shorten the lifespan prematurely.
the best way is to keep them under compression, which means I'll have to fabricate a frame to hang the silencer & rest down on the bobbins.
started with these two brackets using the only stainless bar I have available.
welded the lower bracket under the chassis beam and installed the new frame & bobbins
Using the previous mount to help keep the silencer perfectly positioned/aligned to the bumper while I tack weld this new frame in place.
but afterwards I realised the two different vertical & lateral mounts were actually locking each other in place, DOH!
impossible to cut the old mount off with my bulky grinder or dremel, so I slowly hacksawed it off ?
welded it all up
I've essentially created a carry handle for the exhaust lol ?
fits much better and now cusioned on rubber mounts with minimal movement ?
I'd like to add a 3rd lateral supporting bobbin to stop it swaying sideways but I can always add that later on
now I can finish reassembling the rear suspension
