manowar77 Posted January 3, 2010 Report Share Posted January 3, 2010 Hello everyone! I think my right front wheel bearing is "going south" as you say:) I replaced the left front wheel bearing 2 years ago when the car had around 125.000 miles on it! It was some slack in it back then so i replaced it, no slack in the right bearing at that time! Now,the car has around 140.000 miles and i suspect the right bearing need replacement. Im gonna jack the front up soon and check the right front tire for slacks! But i wonder if the rear bearings need replacent often? I searched this forum for rear wheel bearing replacements but i nearly didnt find any info about it! They are more expensive then the front ones so its maybe built to last longer! Am i right? Or do they fail also sometimes? Roger Roger Martinsen Link to comment Share on other sites More sharing options...
adallak Posted January 3, 2010 Report Share Posted January 3, 2010 I have replaced the both front wheel bearings but at 175,000 the rear ones were still fine. The saddest thing in life is wasted talent Link to comment Share on other sites More sharing options...
JimD Posted January 3, 2010 Report Share Posted January 3, 2010 ....But i wonder if the rear bearings need replacent often? I searched this forum for rear wheel bearing replacements but i nearly didnt find any info about it! Going on memory here, but I would estimate that 90% of the rear bearing replacements I have read about here and on another well-populated Cadillac board have been because of wheel speed sensor failure. FWIW, I have not experienced any wheel bearing (or wheel speed sensor) problems in 190,000+ miles. Jim Drive your car. Use your cell phone. CHOOSE ONE !

Ranger Posted January 3, 2010 Report Share Posted January 3, 2010 Anything can fail Roger. That said, rears seem to be a bit more reliable than the fronts. Link to comment Share on other sites More sharing options...
KHE Posted January 3, 2010 Report Share Posted January 3, 2010 The rears do last longer. Maybe it is because they are not subjected to the powertrain load like the front bearings are. That said, I did have a rear bearing go bad at 180,000 miles on an '86 Park Avenue I used to have. The fronts were fine but one of the back bearings was growling.

manowar77 Posted January 4, 2010 Author Report Share Posted January 4, 2010 86 Park Avenue....Buick,right? Ok, i will also check the rear bearings, but likely its the right front that need replacement! It started, all of a sudden to make a kind of bearing wining sound the other day...just out of nowhere! I read another post on this board from Jan Olsson that seemed to be the same problem, with a wining sound that just started from nowhere and that was one of the front bearings! Thanks for the info, guys! Roger Martinsen Link to comment Share on other sites More sharing options...

manowar77 Posted January 4, 2010 Author Report Share Posted January 4, 2010 I checked the right front today and it had a slack and felt rough when turning it around,so i ordered a new hub bearing today from Rockauto! All other wheels were fine! I replaced the left front bearing 2 years ago, but i do have some questions for you. 1. If i dont remember wrong, the caliper is fastened with 2 bolts,but i dont remember what kind of bolt...10 mm regular bolt or something else? Size? 2. Also the hub is fastened with torex bolts i think...what size? I have the 34mm socket and im gonna buy a 3 armed puller!

KHE Posted January 4, 2010 Report Share Posted January 4, 2010 Roger, The caliper bolts should be 3/8" allen (socket head cap screws) and the hub bolts are either T-55 or T-60 torx but I can't remember the exact torx size.

manowar77 Posted January 4, 2010 Author Report Share Posted January 4, 2010 Thanks KHE! I will buy these tools this week and post an update when i have replaced the hub bearing! Roger Roger Martinsen Link to comment Share on other sites More sharing options...
manowar77 Posted January 9, 2010 Author Report Share Posted January 9, 2010 Update! I replaced right front wheel bearing today and the wining noise is gone! The old bearing was stuck in place because of rust and after using a big hammer and a crowbar it finally came loose! Now the car runs fine without any noise!
