Hi all,


First post but have been using this forum for years to help me fix problems, so thanks to those of you who provide the answers!


I have a 1998 K1500 Suburban, Auto, 5.7L that has developed a squeaking noise in either drive or reverse.


It's really hard to explain but sounds a lot like something you would associate with brakes as it gets quicker the faster you go but seems to dissapear at speed (whether this is because the ambient/wind noise drowns it out I dont know)


I noticed it when reversing down my drive and it occurs in both drive and reverse but completely dissapears if I shift into Neutral whilst coasting.


Hope I've explained it well enough for someone to have an idea of what it is!

Transmission fluid is all good, did a fluid and filter change 6 months ago.


Hope someone can point me in the right direction as here in the UK no-one has parts or knowledge of these trucks so I have to order all parts from the US which is super expensive and takes time!

This is somewhat dangerous...

You could putt it on a Lift, and have someone inside to put it in gear, and idle up to simulate driving. Carefully look/listen to where the noise is coming from.

Be careful.

 

U Joints are dry grease them?

 

Hey uksuburban, did you ever figure out what the squeaking was? I have a similar noise I'm trying to figure out. I posted here:

hoping to find some answers. Any info you might have would be greatly appreciated. Thanks

 

I would remove the rear driveshaft and check for dry/tight ujoints as previously mentioned. They will make a distinct squeak/creak noise that will increase in frequency proportional to vehicle speed.
