Mystery front end knock (clunk) 306
- Thread starter lowpugV2
- Start date
I'll definitely get the gearbox mount checked. Engine mount - I've been assured it's OK but I'm going to get it inspected again at the end of the month - will fully remove the mount to clear look at everything.
Wish I'd known this before putting in the new OEM struts. The front end of the car could do with being lower but I am reluctant to use the eibach lowering springs. Have done that in the past with zero benefit.
Sounds like you rely on others to check things. That is a guarantee you will have to take someone else's word for it, which means in reality you will never know anything for sure.
Actually - that's a good point. Isn't the Phase 3 XSi suspension the same as GTi6?
Unfortunately mate, 2 young kids means that my time under a car is limited, and currently have no locking garage so my tools are locked away at the mother in laws. I inspect what I can but have to trust my local mechanic. Nothing wrong with helping a good local business either!
True, I get it. But I don't think you need to get under the car much. I still think you did not do a proper "cold" (car at rest) test and a drive test. That should yield at lest some results to help you either get closer or at least cross some things off the list. There's not that many things that move in a car.
Same as GTi6 same as xsara vts, same as my car! 2002 convertible. I'd be removing and checking both, the upper top mount has to be removed to see the issue., not simple with the engine in the car nor is the gearbox mount, buffers need to do their job otherwise movement in the mount which cracks the body work around the captive nut.
Every single 2.0l 306 will have the body crack where the top engine mount attaches. Fix is simple and requires welding in a plate at the base of the mounting point. Nothing to worry about.

I've never done it, but if I was going to my approach would be to get an engine crane to support the engine weight. Undo the mount, remove and inspect, then weld. Correct?
Gearbox mount, where is that located?
You are right, my 1.8 style did it. My original XSi cracked at 48000 Kay's, and the GTi6 I had was already welded up. Funny thing is, they never made these sounds! The engine would buck when you lift off and you could feel it move under braking. But never noises.
Gearbox is on the opposite side under the battery etc, bugger to get to. Top is easy in comparison. So battery out, battery box / cover etc ecu etc its under there.
Fortunatel;y my convertible is the exception to all of this. So far.

If a 306 is similar to a Berlingo, I had a knocking sound as well, changed the drop links, top shock bearings, etc no change.
But in the end it was the sway bar bushes that was the problem.
I also discovered that there are 21, 22 and 23 mm dia sway bars.
I measured mine and it was 21mm, and the only place I could get this size bush was from a supplier in Lithuania via eBay.
When I swapped out the old ones, they were marked 22mm, the 21mm ones went in no problem and no more clunking.
My 2c worth.

PS. The ones from OS were $33 delivered and came in 10 days, Citroen dealer quoted $111.00 and a three month wait as there were zero stock in AU.
