Exhaust vibrating against sub frame

klandyg · Jan 25, 2011

Good afternoon all,
After over two months of investigation of a Most Annoying gringing under power i have located the problem! 'Exhaust is vibrating on the subframe under power once Hot '. I hate to admit that i have replaced Quite a few parts before i found the cause, (PROCESS OF ELIMINATION). I have been told it is down to the Manifold and full system replacement will sort issue but Being a K series Petrol i want to get my facts straight before spending any more time or effort on the pig! has anyone encountered this issue before? and if so is there another contributing factor?

You might need to replace these WCS100220 MOUNTING - EXHAUST SYSTEM FRONT | Freelander 1996>: Engine: Exhaust | shop | www.lrseries.com | L. R. Series ,you should be able to pick them up from local motor factors.Could be some other contributing problems.

Yeah, was done yesterday, no change, currently a piece of fire blanket keeping both parts separate to reduce noise although have opened up the weld on middle box, so will need at least some replacing of exhaust system, just want to get to root cause before investing in new pipes.

Surely it's due to a bent mount!
I wouldn't replace any parts until I had fully investigated all the mounting points. Also check the down pipes for an impact point, it may be that the front has had a bash and moved the whole system.

i would agree also check for engine mounts have not gone causing the engine to move about

My early (1998) 1.8 has the exhaust downpipe bolted to the underside of the sump but when I bought it, these bolts were missing and caused an exhaust rattle on acceleration and deceleration. Re-fitting the 2 bolts to secure the downpipe to the sump solved it.
