Question about GMC Safari

2 Answers

I have a 2000 GMC Safari AWD. I just replaced the hubs, calipars/pads, shocks etc. When I accelerate I get strong clicking from the front. It almost feels like gear or shaft splines are jumping. Not sure if that's possible or if its just front shaft bearings. Any ideas ???

    The clicking noise is coming from somewhere in the front drive train. I just replaced the hubs, calipars, pads, and rotors so I know they're all good. Again it feels like front drive shafts are jumping splines (is this possible?) or is it just the cv joints?

    Thanks much! That's actually good to hear. I can replace the drive shafts and joints. I was worried it may be in the transmission/transfer case.

The clicking can only come from one place, and that is one or more the front Constant Velocity drive axle joints, they are the only part that can make this clicking noise, I have 20 years of 4 wheel drive experience and am 99% sure that is is the problem.

Hi,

There are couple of reasons for this clicking noise to come.

It really depends on what is causing it. A loose brake pads would not be something to be too concerned about. If you have a bad wheel bearing or a bad brake pad then it is more serious and should be checked out asap.
OR

it possible that there is something hanging under the dash that is being moved by the brake pedal assy to put the offending componenet in another postion temporarily?

Maybe a relay hanging down that is rattleing against the dash for example?


Thanks for contacting Fixya

Need to replace brakes on 2000 GMC Safari. does it have disc brakes all around or drum rakse in rear?


Disc brakes in the front and drum brakes in the rear. Make sure that you repack the front bearing's with wheel grease before finishing the job.If the front rotors and or the rear drums have a rough brake pad surface,get them resurfaced before installing new brake pads or brake shoes in the rear. you can go online or your public library for complete instructions on how to replace the brakes on that vehicle.

I have a 1993 GMC Safari that started making a strange noise from the front end I have taken it to 2 mechanics they both tell me that the problem is the wheel bearing. 1 says the bearing is in a sealed...


I just re-packed the front end bearings. Haynes covers the brakes real well, but not the bearings. Each front wheel has two bearings (one inside the wheel). So you have to remove the wheels, brakes, dust cap, grease seal and brake rotor to access the bearings. .
Expect to replace the grease seal because the rubber will be brittle or hard. Clean and inspect the bearings and races real well. If the bearings are squealing expect to replace some of them also.
Replacing the brakes so the pads stay in place is the trickiest part.

Sounds like the brake pads is still slightly making contact with the rotor. Replace pads and / or rotor.

Could be that the pads are wore out and are just scraping the rotor. Definately replace pads AND rotor.

Could be that the pads have broken their clips and are flopping around.

Could be a rock stuck in the overall brake assembly.

That's usually an issue with the alignment. Also, make sure the tires are properly inflated, balanced and the right size for the vehicle, as all of those things can cause pulling when you brake. I'd go with alignment first.
