air gun ant 1,666 Posted November 20, 2013 Report Share Posted November 20, 2013 just got my defender back from having some welding done, and for some reason now when im on the motoway it gets to 55-60 mph and a really deep noise starts? with quite a bit of vibration also? it feels like its pretty central to the car. also its only happening when im pressing the throttle, as in if i take my foot of or lighten up a bit it stops? its fine around town and at slow speeds it just seems to be on the motorway or bypass's? as its dark when i get up and dark when i get home i havnt had chance to get under for a look but what should i be checking first do you think? exaust, prop-shaft? any ideas lads cheers ant Quote Link to post Share on other sites

air gun ant 1,666 Posted November 20, 2013 Author Report Share Posted November 20, 2013 (edited) just nipped under at work and theres hardly any play in the rear prop a couple of mm at most but probs a couple of inch in the front? but i did notice that theres some oil around where the rear prop joins the diff?? and at the bottom of the diff also, but that may have run down?

air gun ant 1,666 Posted November 20, 2013 Author Report Share Posted November 20, 2013 Got it on the lift at a mates tyre place and there's a couple holes rusted through the centre section of the exhaust lol there's new ones on eBay with the 2 silencers or there's stainless ones for £15 more that are straight thru, and claim to reduce mpg and improve overall performance " with a deep throaty sound" does anyone have one and did they have any probs with the MOT? Emissions wise I mean? Although how loud is this sound because I don't want to be turning up some of our best drives sounding like a boy racer and scaring birds to the next wood!

tomburras 2,730 Posted November 23, 2013 Report Share Posted November 23, 2013 Iv fitted my 90 with one of theese straight through centre sections 36 pounds from steve parker they make a nice sound and are not too loud even when revving hard. I very much doubt its loud enough to bother anyone. I not had an mot done yet so cant comment on emitions but I cand see it making any difference as its only a silencer. It made a big difference to ground clearence, id recomend one and ill deffo get another one if this blows on me in a few years time. hope that helps! Atb tom. Quote Link to post Share on other sites
