Our differential service consists of diagnostic inspection, repair or replacement of damaged gears, bearings, axles, and seals. The drive axles on a front wheel drive auto are commonly referred to as “CV axles”. The axle boot is the common point of failure. This allows the lubricant to leak out. When the lubricant is all gone from the axle boot, the CV joint starts to make a loud crunching noise. You will be able to identify this noise during your turns. If you hear any kind of noise from the drive axles in a front or rear wheel drive vehicle, Eagle Transmission Shop of North Austin will be glad to diagnose & repair the problem.
