Service Date

Services Performed
  • TEST DROVE THE VEHICLE AND INSPECTED ON THE LIFT. WE FOUND THE FRONT DRIVERS STRUT APPEARS TO BE VERY WEAK AND SEE SOME SEEPAGE FROM THE STRUT. PASSENGER SIDE IS OK. THE LOWER CONTROL ARM BUSHINGS ARE WORN OUT AND HAVE SOME PLAY. SUGGEST REPLACING THE LOWER CONTROL ARM ASSEMBLIES COMPLETE WITH NEW BUSHINGS AND ALSO REPLACE THE FRONT STRUTS WITH NEW BEARING TOPS ON THE STRUT MOUNTS.
  • INSPECTED AND NOTED THE OIL LEAKS AND THE AREAS. CLEANED THE OIL SOAKED AREAS AND RE INSPECTED AFTER RUNNING THE ENGINE FOR A SHORT WHILE. FOUND THE LEAKS COMING FROM THE UPPER AND LOWER OIL PAN. ALSO THE OIL LEVEL SENDER IS LEAKING OUT AT THE BOTTOM OF THE OIL PAN. FRONT CRANKS SEAL IS NOT LEAKING. SUGGEST WE RE SEAL BOTH THE UPPER AND LOWER OIL PANS AND REPLACE THE OIL LEVEL SENDER SEAL – PERFORM A OIL SERVICE AT THE SAME TIME. SEE ESTIMATE FOR THIS RECOMMENDED REPAIR.
  • WHEN WE SCANNED FOR THE FAULTS, THE CODE WAS COMING IN RANDOMLY NOT ALL THE TIME. TEST DROVE SEVERAL TIMES AND SEE WHY THE COMPLAINT IS VALID. AFTER CAREFUL EXAMINATION AND DIAGNOSING – WE COME THE CONCLUSION THAT AFTER THE INSPECTION OF THE CHASSIS WE FOUND THE DRIVE CV AXLES HAVE EXCESSIVE PLAY IN THEM IN THE INNER BALL BEARING CAGE UNDER THE RUBBER GREASE BOOT. THIS PLAY CAN CREATE HAVIC ON THE ABS SYSTEM AND REGISTER A DIFFERENT READING THAT WILL CREATE THE FAULT CODES. WE NEED TO REPLACE THE CV AXLES IN ORDER TO RESOLVE THE COMPLAINT POTENTIALLY. THERE IS NO OTHER FAULT IN THE SYSTEM THAT COULD BE PRESENT AT THIS TIME. THE ABS SENSORS ARE READING CORRECTLY AND ARE ACTIVE AL THE TIME. BUT THE SPEED OF THE TRANSMISSION AND THE WHEELS ARE NOT ALIGNED, WE SUSPECT THE PLAY IN THE CV AXLES ARE CAUSING THE FAULTS. SUGGEST REPLACING THE CV AXLES – BOTH AND RECHECK AFTER THE REPAIR.
  • RELATED TO THE CV AXLES LAGGING IN RESPONSE TO DRIVING.

Service Date

Services Performed
  • PERFORMED VISUAL INSPECTION ON THE VEHICLE. WE VERIFIED THE ENGINE HAS SEVERAL LEAKS ALL AROUND THE ENGINE – VALVE COVERS – V-TEC SOLENOID – LOWER OIL PAN. WE COMPLETELY AIR PRESSURE CLEANED WITH CHEMICAL DEGREASER TO BETTER IDENTIFY THE OIL LEAKS. AFTER THE CHEMICAL CLEANING WE CAN STILL SEE THE SAME LEAKS LEAKING OUT RIGHT NOW. POSSIBLE A FRONT CRANK SEAL OI LEAK AS WELL. OTHER ITEMS OF CONCERN ARE THE FRONT SUSPENSION IS BOUNCING AND FEELS WORN OUT. CAN FEEL A CLUNK IN THE FRONT SUSPENSION, SUSPECT THE FRONT STRUT MOUNTS ARE FAULTY ALONG WITH THE STRUTS. FRONT STEERING TIE RODS ALL OF THEM HAVE EXCESSIVE PLAY IN THEM. TOO MUCH SIDE TO SIDE PLAY IN THE STEERING. FRONT CV DRIVE AXLES ALSO HAVE PLAY IN THEM. THIS WILL CAUSE A FUNNY SENSATION IN THE FRONT END WHEN DRIVING AND STEERING . WE SUGGEST ALL THESE EXTRA ITEMS TO BE ADDRESSED AS WELL AS THE OIL LEAKS. SMOKE OUT THE TAIL PIPE MAY BE CAUSED FROM THE OIL LEAKS LEAKING INTO THE EXHAUST AND OR THE ENGINE MAY BE TIRED FROM EXCESSIVE WEAR DUE TO POTENTIAL OIL SERVICES THAT WERE NOT PERFORMED ON THE TIME TABLE REQUIRED.? SUGGEST REPLACING THE ENGINE ASSEMBLY WITH A LOWER MILES IMPORTED "JDM" ENGINE AND REPLACE ALL THE ASSOCIATED COMPONENTS WITH GASKETS AND ALL THE FLUIDS NEEDED. SEE ESTIMATE FOR ALL THESE CONCERNS.
