Q2 What is the recommended torque specification for the front suspension strut bolts?
What is the recommended torque specification for the front suspension strut bolts?
The recommended torque specification for the front suspension strut-to-steering knuckle bolts is 90 Nm (66 lb-ft) plus an additional 90-degree turn. Always use a torque wrench and follow Audi's tightening sequence to ensure proper installation and safety.
Q3 How do I identify wear in the Audi TT suspension components?
How do I identify wear in the Audi TT suspension components?
Common signs of suspension wear include uneven tire wear, excessive bouncing, knocking noises over bumps, and a noticeable drop in ride height. Inspect the shock absorbers, bushings, and ball joints for leaks, cracks, or play. Use a dial indicator to measure ball joint play, which should not exceed 0.8 mm (0.03 in).
Q4 What is the ride height specification for the 2006-2014 Audi TT?
What is the ride height specification for the 2006-2014 Audi TT?
The factory ride height for the 2006-2014 Audi TT is approximately 135 mm (5.3 in) at the front and 130 mm (5.1 in) at the rear, measured from the wheel center to the fender lip. Variations may occur depending on the trim level and optional suspension packages.
Q5 Can I install aftermarket lowering springs on the Audi TT suspension?
Can I install aftermarket lowering springs on the Audi TT suspension?
Yes, aftermarket lowering springs can be installed, but they must be compatible with the Audi TT's suspension geometry. Lowering the vehicle by more than 30 mm (1.2 in) may require additional modifications, such as adjustable camber arms or revised shock absorbers, to maintain proper alignment and handling.
Q6 What is the recommended alignment specification for the Audi TT suspension?
What is the recommended alignment specification for the Audi TT suspension?
The factory alignment specifications for the 2006-2014 Audi TT are: Front camber -0°30' to -1°00', front toe 0°05' to 0°15'; Rear camber -1°30' to -2°00', rear toe 0°10' to 0°20'. Always perform alignment adjustments using Audi-approved equipment and procedures.
