noise

[The Radman]

im hoping someone on here has had the same problem and can help with this as im running out of ideas what happens is on the overrun i get a rumbling type of noise,mainly noticeable in 3rd and 4th but only when the revs drop to around 3000rpm,the slightest bit of throttle and it stops again,it sounds exactly like when the down pipe is catching the bodyshell except it isnt,i run a standard exhaust so theres loads of room,at first i thought it was the rear diff so ive tried another and no difference,the weird thing is when its making the noise if you put the clutch in it stops it,let it out and it continues,applying the brakes makes no difference but if you put the h/brake on fully it stops it,let the h/brake off again and it starts again
all the mounts are fine/new,ive swapped exhausts,ive removed the h/brake cable completely,ive renewed the prop bearing and rubber insulator,the uj feel fine and tight,i know kev on here had the same thing and he also renewed the transfer chain and front diff and made no difference either,its got a new clutch/release bearing, the g/box seems spot on [its only done 25k] it drives spot on with no noises or anything at all apart from this one,any ideas?
rear cv joints are next on my list if i cant think of anything else

Was talking about this today with my mot tester(has a bt escos also) mine has had the same noise for a year now and its time to sort it , he pointed straight to the transfer chain, was going to remove my box and send it away to get sorted but if youve done yours i'm back to square one again would welcome some advice also.

[The Radman]

ive not done my transfer chain but when i had the box out for my resto it looked fine with no real play in it

Are you using O/E mounts throughout?, engine, gearbox, rear beam, trailing arms, exhaust etc?.
its suprising what noise/vibration the standard stuff soaks up.

[stu]

mines all standard but noise defo sounds more mechanical fault i.e diff or gearbox but the description of yours is exactly the same as mine

im in the process of fitting standard engine mounts,all the rest are standard and new apart from rear trailing arm ones as at the time nobody remade them so had to use polys

I had something simmilar, it was the front propshaft joints.

[ESCORT2483]

mine had same as you know nick .. i sent you text , saying transfer chain as i did all sorts to mine to try and sort too .. i reckon it could be that notchy rear uj on rear propshaft .. i believe you said yours was a bit notchy too

[Matty]

It's still there Mark only really in 4th I took no notice of it as my last one did the same.

[The Radman]

the prop isnt notchy mark,only when you swivel it straight can you feel it click into the little notch if you know what i mean

[The Radman]

cant beleive this is a pretty common problem then,but nobodys ever cured it

[Matty]

I had a similar problem on my saph the prop clicked as you moved it in one direction other way was fine I took it to propshaft services by me and the guy there told me it was fine but I was not convinced so I had him change the uj anyway and balance it which cured the problem.
But that was a vibration probmem not this weird rumbling.

[cossimc]

Mine does the same or should I say did when lifting off throttle sounds like exhaust rattle my trip to ford fair at the weekend fixed this problem for some strange reason a good few miles must of done it well

[ESCORT2483]

thats what i am saying nick .. the uj should move smoothly in all directions . it SHOULD NOT click into place . inside there are needle roller bearings , and they have a habit of wearing or breaking up

[The Radman]

it doesnt click mark [as in make a noise] ,i meant you can feel a sort of notch when you swivel it into the straight position,theres no play whatsoever
