Squeal in Rear


Recommended Posts

Hey all,

I just joined today and was checking out the 996TT/GT2 forum.

I have a 2003 996 TT X50 stock and a 2002 996 TT non X50 stock (added Baileys and GT2 intercoolers to the 02 though). Both cars have an annoying ailment I have not had any luck finding the culprit so I am posting here to see if anyone has experienced or resolved this issue.

At decelleration in gear or out of gear - however more so in gear at about 2000-1800 RPM's (usually in second gear) the car exhibits a loud metal on metal sounding squeal. Sometimes it goes away when I depress the clutch sometimes not. I have had the car in and was able to reproduce the sound while at idle - it seems to be coming from the power steering pump however two line replacements (thought it might be a sticking check valve) and a pump replacement on the 02 and no luck.

I am curious if anyone has heard this happen and if anyone has any luck resolving the issue. I'm beginning to wonder if it is a bearing beginning to bind in the belt train but upstream of the power steering system and the noise is being transmitted to the power steering pump?????

Your thoughts and input is greatly appreciated!!! Thanks for the feedback!! T2

I have noticed what I would describe as a slight buzzing sound when decelerating in gear towards a stop (not using the engine to slow down, but brakes on prior to pushing in the clutch). The gear that I'm in does not seem to matter, and I haven't paid attention to the rpms at which it occurs as it happens all the time. It goes away every time immediately upon initiating clutch depression.

The sound is almost inconsequential, but I do monitor it to ensure that it does not worsen and become a harbinger of some sort of bad thing. fwiw.....

ciao for niao
