Our somewhat weary Corolla 1.3 12 v/v 5 speed manual has recently developed a sort of erratic clinking/clunking sound from the front end. It is not the sort of loose sounds you get from something hanging loose, more a 'greasy' engine sort of clonk. Sometimes on dead flat road, but usually where it is a little rough.

Several inspections and replacement parts have solved nothing. Local guys replaced the outer CV joints and front struts a few months back, but the noise has appeared since then, though not immediately after.

I have looked myself and all I can see that is amiss is the inner CV joint housing appears to move radially a few mm. I know it runs into a spline, with a seal, but nobody seems to be able to tell me how much play is acceptable. The CV joints themselves seem okay, no movement in them.

Do these inner CV joint housings simply pull out, or is there a Circlip on the inside?

There was also a sort of whirring sound that appears as speed builds up, and doesn't disappear when the clutch is dipped. Yesterday we changed a rear wheel bearing and this seems to have disappeared, but I've only driven it briefly since then.

The cv's are held in with a snap ring they should come out with a sharp pull a little bit of play is normal if the splines wear out (very unlikely) you will get slippage under heavy load and soon after loss of drive!! I would be looking at anti roll bar links, suspension, bushes, springs, mountings..

Suspension geometry will require the drive shaft to move in and out which is why there is a spline rather than a bolted flange.

Check engine mounts as well as suspension bushes. The whirring may be something rubbing now the engine mount has given out/moved.

The driveshaft does not move in & out on the splines/gearbox on the Toyota Corolla frown that's the inner CV's job wink King Herald as mentioned already look for up and down play on the front anti-roll bar drop links even the smallest amount of play will drive you nuts mad

I've pulled and pushed and banged on everything I can see, so have the garage guys (to a degree) but I can find nothing obvious. I go offshore again tomorrow so it'll have to wait until I get back in six weeks now. Maybe something obvious will develop while the wife is driving it. If there's nothing we can see wrong then I think it is still safe to drive.

Normally proper car technicians will know exactly where to look for problems on particular cars, but this is the Philippines and well, 'technicians' here are not what they could be.

Still, engine oil change, gearbox oil change, one new rear wheel bearing, all four brakes inspected, and a general under-chassis inspection: £50 biggrin
