Hi guys
When at low speed, i mean at 10mph there seems to be a kluncking and rattling sound comming from the back and the will not pull away smoothly, there is no play in the prop joints or wheel bearings, could this be a diff problem? is there a place in southend on sea or a surrounding area then can modify the exhaust to sound better. Cheers!!!

Hi Richard
If you need new bushes on the diff mount you can now get the same tougher rubber as the top mount on the two lower mounts.
I let TVR Power in Coventry do all the work on mine and I'm a fellow Sarfenda!
As for the exhaust you can remove the pre-cats in the manifolds for a better sound but doesn't make a huge difference.
Other options include having solid pipes welded inside the silencer for a huge sound but you may struggle with track day noise regs, assuming you going to do any. There is also the cherry bomb conversion, do a search on this for more info.

Could be the Diff bushes - had similar on mine last year. If it's the 2 front bushes it's a cheap replacement. Price goes up a fair bit though if the top mount also needs doing as it's a PITA to get at. Had all mine replaced with Poly bushes which are much longer lasting and the same price as the originals.
Thanks guys, so there are generally no problems with the diff itself only the bushes? i was haveing a right old worry up over this seing the old wallet drained, as if my wife hasnt drained it enough over xmas, bloody hell Dave Coventrys a long way to go to have a bit of work done, nothing local then?
You probably have a GKN, but its quite easy to tell. Look up the driveshafts & the BTR diff has toothed sensors between diff & driveshaft (for ABS I guess ~ but used on the passenger side for the speedo), the GKN has a toothed wheel (crown) between the propshaft & diff.
Just as a warning: the GKN is rarer, and casings + crown wheel can eat each other, when bearings fail. These parts can only be salvaged from other diffs, and where becoming hard to find a few years ago ~ so v expensive. There may be more 'retired' cars now so that there are a few available ~ but it will still cost a lot if you run the diff when it is graunching.
You really need to get under the back end (on ramps) and give it a good inspection.
