NSF Knocking sound

Previously there was a knocking sound which presented itself on some occasions while driving. The knock tempo increased as I increased speed and the tempo reduced as I reduced speed then went away for a week or two.

When this happened the knocking was loud as if someone was knocking on the car and the car was made out of wood.

Today I noticed a much quieter knocking but I can feel the vibration of the knock through the accelerator pedal.

I looked at the CV Boot and the end of the driveshaft nearest the wheel and it looks like there is Oil all over it, I know I have a problem.... is it major?

Re: NSF Knocking sound

So the boot needs replacing and the Joint needs a lube and I'm good to go again?

I don't need a new CV Joint do I?

Re: NSF Knocking sound

I don't think I'm qualified and knowing my luck I'll get this close |.| and either break something or not have the correct tools, on top of that I doubt I'll have the time to do it anytime soon

Whats the worst that could happen if I continue to drive on it? its not the Gearbox end so I'm hoping I won't make the damage even more expensive then it is

I will get it fixed but I'll have to make an appoinment at a garage which could take a while depending on when they are available for me to drop Tipo off and pick it up.

Re: NSF Knocking sound

eventually the CV joint will break up and you lose drive.TBH ive driven them for ages before fixing them
its not a hard job.
undo the hub nut
undo the track rod end & lower ball joint.seperate both with a balljoint seperator
undo the inboard side of the driveshaft
undo the hub mounting bolts
remove the driveshaft by moving the hub assembly outwards

to revove the CV you need to pull back the CV boot and open the circlip(messy fiddly bit)
remove old CV.
its then pretty much a reversal to refit with a new hub nut

Re: NSF Knocking sound

..........

You make it read easy, just like when the Haynes said it was a minor to remove the dashboard, lies it was, lies I may give it a try.... but more then likely not.

Thanks for your help custard ever thought of owning a Tipo?

Re: NSF Knocking sound

OK the CV boot was looked at and apparently is wasn't wet/oiled enough for it to be a problem, that knocking sound I heard decided to up and leave when I took two mechanics for a test run, one of them took the car out and drove it hard, nothing, not a whisper.

The tapping sound on the strut mount maybe the strut rubber which has worn away.

They both found one problem though......

The NSF Koni Adjustable Shock may need replacing as it moves up and down easier then the other 3 @ 175 I'm hoping it just needs adjusting.

Don't say that I usually buy in pairs when it involves a left and right but the right one still feels like its been overdosed on viagra.

Re: NSF Knocking sound

If ordering my adjuster screws and adjusting the shock doesn't fix m problem and repairing is cheaper then replacing then yeah I'll do that... doesn't that mean I'd have to do them both though to make sure they are balanced?

Re: NSF Knocking sound

Possibly, or at least send both away so the left can be balanced to the right. How long have you owned the Koni's for? My gd's dad's sedici has Koni Adjustables. Is yours lowered?

Re: NSF Knocking sound

info courtesy of PSC

sports strut for a mk1 punto cost around £130 each from demon tweeks.

A company who's name i'm unsure can repair them.

tel. 01280 702633

They have quoted approx £30 for a new adjuster rod, fitted plus p&p each way.
So its probably going to cost about £40 in all, which is gonna savs about £90 by not buying a new strut.

This company only deal with koni shocks and will repair them, even oil seals etc.
