(You save)
Keep the front right upper corner of your suspension tight and precise with the Delphi control arm and ball joint assembly, part number TC7638. This front right upper unit installs as a direct-fit replacement for the 2001-2005 Lexus IS300, combining the arm and its pre-installed ball joint into one piece — the part many owners of the 2001-2005 Lexus IS300 shop for as an upper control arm.
OE-tested durability: withstands temperatures below -40°C and over 120°C plus 720 hours of salt spray, with extensive dimensional and material analysis for OE-to-aftermarket compatibility.
Verified integrity: undergoes 100% crack detection and ultrasonic flaw detection so materials match OE specifications.
Precision ball stud: machined to micron tolerances for durability and smooth joint operation, with robot welding for consistent quality.
Anti-corrosion protection applied to each part for corrosion prevention and enhanced aesthetics.
Signs the original front right upper arm or its ball joint may need replacing include clunking over bumps, steering wander, or uneven tire wear; if a worn arm or joint is the cause, this assembly replaces both at once. Sold individually — replacing both sides together is recommended, and the opposite side is sold separately.
It is a direct-fit replacement for the 2001-2005 Lexus IS300 in the front right upper position. See the Buyer's Guide tab to confirm fitment for your vehicle.
Which position does this control arm fit?
It is built for the front right upper position, as listed in the catalog.
Is the ball joint included?
Yes. The ball joint comes pre-installed in the arm, so you replace the control arm and joint together as one assembly.
How many do I need for a full replacement?
This listing is for one arm covering the front right upper position. Replacing both sides together is recommended; the left-side part is sold separately.
What are signs this control arm may need replacing?
Clunking over bumps, steering wander, or uneven tire wear can point to a worn arm or ball joint. Have the front end diagnosed before replacing, since other parts can cause these signs.
