Thanks Gary, I found very little when i researched this and thought this could be useful. I will make another thread on the cleaning and doing all the bushings.

Brilliant Lee, really helps me out with my winter project, I have the trailing arm bush removal tool if need to borrow it, just cost postage and return.

It's well worth getting the axle and trailing arms powder coated while they are off

 

[Lee]

Funny you should say that i do need the removal tool. If i had more time i would take them into work and do just that. I'm happy to send a postage fee to you if you wouldn't mind. (pay-pal email)

I have a few days to rest waiting for the bushes and new tank to arrive.

Lee, well put together and I'm sure will be helpful for many years to come. What I enjoy about articles like this is it isn't just a how to for the tank but also mini how to's for other components. Glad you didn't have to do it in the snow!! JIM

Jim I may have snow when I do it, will ensure it's included in any photo's for you!

hi lee just read your excellent write up about petrol tank rattle i think it well describes my problem exactly ...i was thinking is the ball metal ...is there a service hatch near that i could put a large magnet through to hold the ball ?

Now that's a brilliant idea!

Hi again do you think it might work ? if there is no service hatch near where would the best place cut one ie inside boot or behind a seat ?

I doubt it guys. That metal ball is a safety item best not to lock it open.
